0:00:22 > 0:00:23in Alberta, Canada.
0:00:26 > 0:00:29No-one's been killed but many parts of the city have been destroyed
0:00:29 > 0:00:31and officials say the fire could double in size
0:00:31 > 0:00:34in the next 24 hours.
0:00:34 > 0:00:37People who live there are leaving, but the fires have meant one
0:00:37 > 0:00:40of the roads has become too dangerous to travel on.
0:00:40 > 0:00:42Hundreds of sick and injured servicemen and women
0:00:42 > 0:00:44are getting ready to compete in the Invictus Games,
0:00:44 > 0:00:54which start this weekend in Florida in the US.
0:00:55 > 0:00:57One Team UK competitor is former guardsman Lamin, who was
0:00:57 > 0:00:58injured in Afghanistan.
0:00:58 > 0:01:01I've been to meet his 12-year-old son Musa who is going
0:01:01 > 0:01:02with him to the games.
0:01:02 > 0:01:03A message?
0:01:03 > 0:01:04Oh, from Michelle.
0:01:04 > 0:01:06The Invictus games already has the royal seal of approval.
0:01:06 > 0:01:09Be careful what you wish for.
0:01:09 > 0:01:11Even the US President Barack Obama is ready for action.
0:01:11 > 0:01:12Really?
0:01:12 > 0:01:14Please.
0:01:14 > 0:01:19Boom.
0:01:19 > 0:01:22The games begin on the 8th of May in Orlando in America and will
0:01:22 > 0:01:25see injured servicemen and women from all over the world go
0:01:25 > 0:01:29head-to-head in a whole host of different sports.
0:01:29 > 0:01:32Prince Harry came up with the idea of the games two years ago.
0:01:32 > 0:01:4212-year-old Musa's dad is taking part.
0:01:42 > 0:01:45Lamin lost both his legs and an arm during the war in Afghanistan.
0:01:45 > 0:01:49When we were just sitting down and watching football,
0:01:49 > 0:01:51he came in with his wheelchair, he came running fast,
0:01:51 > 0:01:54and said, "I'm going to be in the Invictus games!"
0:01:54 > 0:01:56How difficult is it for your dad to get
0:01:56 > 0:01:59around everyday?
0:01:59 > 0:02:06Life is hard for him because, you know, he doesn't get to
0:02:06 > 0:02:09do most of the things a father would do with his son or his daughter.
0:02:09 > 0:02:10He's just laying down.
0:02:10 > 0:02:12He needs help to travel around.
0:02:12 > 0:02:14He should be helping the children and the wife, but
0:02:14 > 0:02:15instead are helping him.
0:02:15 > 0:02:19He feels vulnerable.
0:02:19 > 0:02:23Why do you think the Invictus Games are so important?
0:02:23 > 0:02:26It's so important that we can help the wounded and the hurt
0:02:26 > 0:02:28to know that they have a meaning in this world.
0:02:28 > 0:02:30Not that they're just hurt and they can't do anything.
0:02:30 > 0:02:38So, Musa, there's one last thing for us to do, isn't there?
0:02:38 > 0:02:40Should we wish your dad the best of luck?
0:02:40 > 0:02:41Let's go.
0:02:41 > 0:02:42BOTH: Good luck, Dad.
0:02:42 > 0:02:46Boom!
0:02:46 > 0:02:49Finally, to some fantastic pictures from the deepest place on earth -
0:02:49 > 0:02:50the Mariana trench.
0:02:50 > 0:02:52It's about seven miles under the Pacific Ocean
0:02:52 > 0:02:55and because it's so deep, not a lot is known about the area.
0:02:55 > 0:02:56Cameras have captured creatures like jellyfish,
0:02:56 > 0:02:58ghostsharks and rabbit fish.
0:02:58 > 0:02:59We're back right here just after midday.
