:00:14. > :00:21.temperatures, emergency rooms on alert. During 100 degrees across
:00:22. > :00:29.much of the country. And the double jeopardy tornado. The same part of
:00:30. > :00:32.the country hit by a tornado twice. Militants arrive at the oilfields of
:00:33. > :00:50.Iraq, already affecting gas prices and home. Good evening. We begin
:00:51. > :00:55.with the record high temperatures and the map says it all. More than
:00:56. > :00:59.half the country had temperatures above 90 degrees, and many places
:01:00. > :01:02.approached 100. The first round of heat is often the toughest on the
:01:03. > :01:08.body. Some schools let children out early. And then there was this, a
:01:09. > :01:18.monstrous tornado touching down. It hit in nearly the same place. How
:01:19. > :01:21.long will this last? Three days until the official start of summer,
:01:22. > :01:27.and the east coast is already breaking records. In Philadelphia,
:01:28. > :01:36.it was 94 degrees. Is ridiculously hot. So used to snow days, instead,
:01:37. > :01:43.children were sent home because of the heat. At the US Open, fans were
:01:44. > :01:47.struggling. Washington, DC was the hottest city in the country, with
:01:48. > :01:54.temperatures climbing to 94 degrees. Over 90 degrees for the third day in
:01:55. > :02:00.a row. Ice cream and stay in the shade. The first heat wave of the
:02:01. > :02:04.season can be a shock. It can be hard to actor made to axe 82 extreme
:02:05. > :02:10.temperature changes. Stay prepared. `` it can be hard to get used to
:02:11. > :02:14.extreme temperature changes. Stay prepared and drink lots of fluid.
:02:15. > :02:21.Especially when you are working outside. I have water here. And get
:02:22. > :02:25.ready for more. Above normal temperatures are being predicted for
:02:26. > :02:30.both coasts and the south this summer. Meanwhile in the West, heat
:02:31. > :02:34.and gusty winds are fuelling this wildfire in New Mexico, burning more
:02:35. > :02:39.than 20 square miles and threatening homes. It is so dry in parts of
:02:40. > :02:44.California, farmers are resorting to an old technique which uses the
:02:45. > :02:50.moisture stored in the soil to grow crops instead of relying on rainfall
:02:51. > :02:55.or irrigation. These past few years, we have had successful crops even
:02:56. > :02:59.though we are in drought. And this is just a preview of what is to
:03:00. > :03:06.come. This summer could be one for the record books. And we are also on
:03:07. > :03:12.the ground after those twin twisters early in the week. Another giant
:03:13. > :03:19.tornado touchdown and not far away. Where will it go next? First, our
:03:20. > :03:26.correspondent is there. Talk about frightening. This large, powerful
:03:27. > :03:32.tornado, hovering above farms in Nebraska, hold still the nearly 40
:03:33. > :03:38.minutes. The average tornado moves quickly, 35 mph or more, but this
:03:39. > :03:44.one does not move at all. When it does move, just 5 mph, destroying
:03:45. > :03:49.farms and killing livestock. At night, this is what was hiding in
:03:50. > :03:52.the dark, another tornado that families were not able to see until
:03:53. > :03:56.lightning struck and lit up the sky. In Nebraska, where those twin
:03:57. > :04:01.tornadoes killed two people, families cleaning up are hoping for
:04:02. > :04:07.better conditions tonight. Maryanne has lived here since 1972. Her home
:04:08. > :04:13.was badly damaged by one of the twisters. Have faith in God and he
:04:14. > :04:19.will be due to the next step. That is being tested. In South Dakota, a
:04:20. > :04:24.tornado hit a farm with nearly 120 mph winds. Part of the decoders are

:04:36. > :04:50.tonight. Thank you for joining us. 70 million people are in this area,
:04:51. > :04:54.where there is severe weather. All the way from Canada to Mexico, and
:04:55. > :04:58.to the east coast. We are concerned about large hail, strong winds, and
:04:59. > :05:03.even tornadoes that we had overnight. What about the heat, what
:05:04. > :05:08.kind of temperatures and humidity are we looking at? It is not only
:05:09. > :05:13.the heat but the humidity. Our bodies call less efficiently when
:05:14. > :05:16.humidity is high. That makes them dangerous conditions. In Washington,
:05:17. > :05:24.DC, record highs yesterday. Close today, when you factor in humidity,
:05:25. > :05:29.it feels like more than 100 degrees. Caller tries to make its way in from
:05:30. > :05:34.Canada `` cooler air. We still feel muggy conditions, and all the way
:05:35. > :05:40.through the weekend. Look at these temperatures, up close to 100
:05:41. > :05:43.degrees again. Two other breaking headlines this
:05:44. > :05:48.Wednesday night, militants in Iraq have made it to the oilfields, this
:05:49. > :05:52.is what many had feared, our correspondent is in Baghdad with
:05:53. > :05:58.what these militants could do with their new`found powers.
:05:59. > :06:02.It is the critical lifeline, Iraq's biggest oil refinery is partially
:06:03. > :06:06.ablaze. If the militants take it, they would have the ability to
:06:07. > :06:12.control the sale of gasoline and cut power across parts of Iraq. Tonight,
:06:13. > :06:16.they have the upper hand. A US official told ABC News that it is
:06:17. > :06:22.only a matter of time before the refinery is overtaken. Iraq today, a
:06:23. > :06:33.deadly battle ground. Seen up close by a team with partners from the
:06:34. > :06:38.BBC. All got out alive this time. With city after city falling, it is
:06:39. > :06:42.the militants with the momentum. Late today, President Obama meeting
:06:43. > :06:47.with congressional leaders on next steps. All indications are that he
:06:48. > :06:50.will not order large`scale air strikes. The administration did not
:06:51. > :06:54.want to bolster the Iraqi government, that has failed to unite
:06:55. > :06:59.its people. We have done everything that we could to help them. It is up
:07:00. > :07:03.to the Iraqis. Air strikes are risky. As illustrated in this video.
:07:04. > :07:07.The militant fighters seen from the ground, they are easy to distinguish
:07:08. > :07:13.from civilians who would circle them. It is far more difficult from
:07:14. > :07:20.the air. It is not as easy as looking at an iPhone video of a
:07:21. > :07:24.convoy and then striking it. The US has eyes in the sky, carrier `based
:07:25. > :07:30.F`18s from the Persian Gulf are flying over Iraq, as well as other
:07:31. > :07:34.surveillance aircraft. Tonight, all eyes remain on that critical oil
:07:35. > :07:39.refinery that has been targeted, showing how strategic the militants
:07:40. > :07:45.can be. The situation remains dangerous tonight.
:07:46. > :07:48.All week long we have followed the impact here at home, tonight, new
:07:49. > :07:54.numbers and gas prices, economists say that Iraq is to blame. Our
:07:55. > :07:59.correspondent is in California. You can see that playing out here.
:08:00. > :08:03.Have a, look prices above $4 per gallon. At this station, and they
:08:04. > :08:10.have been rising through the country. Look at these numbers out
:08:11. > :08:14.tonight. Now the prices of this. Some say that drivers could expect
:08:15. > :08:18.to pay as much as 5 cents per gallon. All because of these fears
:08:19. > :08:22.over what is happening in Iraq. You have told us about the other
:08:23. > :08:25.headline for American drivers, where Democrats and Republicans are
:08:26. > :08:32.considering raising federal taxes on gasoline? Yes, an announcement from
:08:33. > :08:36.Washington today, they could raise that tax by 12 cents over the next
:08:37. > :08:40.two years to pay for roads and mass transit, potentially more top News
:08:41. > :08:45.the drivers out there. We will watch that. It is affecting so many

:09:04. > :09:07.high`level employees have lost their jobs. Tonight, we look at the
:09:08. > :09:11.stunning images, our team watching as children cross the American
:09:12. > :09:18.border, many alone without their parents. This search heading north.
:09:19. > :09:23.We look at where these children end up. Inside the hunt for an
:09:24. > :09:29.unprecedented flood of Central American children, some with
:09:30. > :09:33.parents, and some coming alone. Sneaking into the USA, along the
:09:34. > :09:42.southern border. Helicopters above, border patrol agents blow, `` below.
:09:43. > :09:48.It is happening a thousand times a day, in Texas, unheard of numbers.
:09:49. > :09:53.Mothers bringing babes in arms across the river, into the United
:09:54. > :09:58.States. This woman, from Honduras, collapsing into the arms of an
:09:59. > :10:04.agent, when he says that she is in the USA. This young man is 17,
:10:05. > :10:08.crossing alone. These two, only children, spending six days riding
:10:09. > :10:20.buses and walking here from El Salvador. I asked how old he was.
:10:21. > :10:26.16? Only 16 years old, alone, taking his sister to join his mother in
:10:27. > :10:29.Georgia. She is only 12 years old. They smiled at me nervously when I
:10:30. > :10:36.told them that they were only children. Where will they go next?
:10:37. > :10:42.You are overwhelmed for space? Yes, it is a challenge. The first stop in
:10:43. > :10:45.the USA for them is here. The overwhelmed and overcrowded
:10:46. > :10:53.processing centres of the US border patrol. The American dream begins on
:10:54. > :10:57.a concrete floor here. We will stay on this story, we move
:10:58. > :11:01.on here this evening, to what could be a revolution coming to your smart
