0:00:05 > 0:00:06Hi, this is Newsround.
0:00:06 > 0:00:09I'm Ricky with all you need to know this Saturday.
0:00:09 > 0:00:13Coming up...
0:00:13 > 0:00:15The latest on the wild fires in Canada.
0:00:15 > 0:00:17And - cute alert!
0:00:17 > 0:00:26We meet a baby dolphin born in the US.
0:00:26 > 0:00:27First, huge wild fires are continuing in Fort McMurray
0:00:29 > 0:00:31in Alberta, Canada.
0:00:31 > 0:00:35No-one's been killed but many parts of the city have been destroyed.
0:00:35 > 0:00:41I've been taking a closer look at the latest developments.
0:00:41 > 0:00:46The fire started last Sunday and Canada's Oil Sands region.
0:00:46 > 0:00:49Experts say it was able to spread due to the unusual weather,
0:00:49 > 0:00:59which has caused more dire condition than normal.
0:00:59 > 0:01:00-- dryer.
0:01:00 > 0:01:03Alberta has had 330 wildfires already this year, more than double
0:01:03 > 0:01:05the amount they would usually have in 12 months.
0:01:05 > 0:01:0888,000 residents were evacuated and nine evacuation centres were set
0:01:08 > 0:01:10up in Alberta by Thursday evening.
0:01:10 > 0:01:12We had, basically, two minutes to get home,
0:01:12 > 0:01:14grab our staff and then we had to leave.
0:01:14 > 0:01:18A huge team of firefighters, helicopters and air tankers
0:01:18 > 0:01:20are battling the blaze.
0:01:20 > 0:01:23The fire now covers an area larger than New York City and is expected
0:01:23 > 0:01:25to double in size in the coming 24 hours.
0:01:25 > 0:01:31Thousands of miles away, volunteers in Toronto have been
0:01:31 > 0:01:35providing aid packs to those affected by the wildfires.
0:01:35 > 0:01:36I just wanted to help.
0:01:36 > 0:01:37There's not much we can do.
0:01:37 > 0:01:38We feel helpless here.
0:01:38 > 0:01:41While aid begins to reach those affected, the Canadian Government
0:01:41 > 0:01:48is working to find temporary housing for family to foster homes.
0:01:48 > 0:01:51A total of 40 wildfires are still burning with five out
0:01:51 > 0:01:53of control, and that is causing problems for people trying
0:01:53 > 0:01:56to evacuate their homes as one of the main routes out
0:01:56 > 0:01:59of the area has been covered with heavy smoke.
0:01:59 > 0:02:01Luckily, people have acted fast and, with no casualties, people
0:02:01 > 0:02:11are hoping these files will let up so they can move on in their lives.
0:02:11 > 0:02:12-- fires.
0:02:12 > 0:02:15In Australia, the city of Sydney has been blanketed in smoke
0:02:15 > 0:02:17after firefighters there carried out controlled burns in
0:02:17 > 0:02:18the nearby countryside.
0:02:18 > 0:02:21People who live there woke to find famous landmarks hidden.
0:02:21 > 0:02:25Asthma-sufferers have been advised to stay indoors
0:02:25 > 0:02:26until the smoke dies down.
0:02:26 > 0:02:29It's hoped that by lighting carefully managed fires in the dry
0:02:29 > 0:02:31bush areas near the city, destructive wildfires
0:02:31 > 0:02:41will be prevented.
0:02:41 > 0:02:43Meanwhile, police in California, in the US, are tackling a different
0:02:43 > 0:02:45kind of extreme weather, this huge mudslide.
0:02:45 > 0:02:48It closed a major road in the State, leaving drivers stranded.
0:02:48 > 0:02:49It was caused by heavy rains.
0:02:49 > 0:02:51The results are coming in after elections took place
0:02:51 > 0:02:52across the UK on Thursday.
0:02:52 > 0:02:55One of the big stories is in London, where people have voted
0:02:55 > 0:02:56to choose a new mayor.
0:02:56 > 0:02:59We asked the BBC's man in the know to explain more.
0:02:59 > 0:03:01Here's Chris Mason.
0:03:01 > 0:03:03Over the last few days, there have been lots of,
0:03:03 > 0:03:05what are known as, elections.
0:03:05 > 0:03:08Where grown-ups get a say on who's in charge, who is running things,
0:03:08 > 0:03:10which politicians get to make decisions.
0:03:10 > 0:03:13We have just found out who will be the new Mayor of London
0:03:13 > 0:03:20for the capital city.
0:03:20 > 0:03:23Because London is such a big city on the world stage,
0:03:23 > 0:03:25this matters for everyone - wherever you are in the country.
0:03:25 > 0:03:27It used to be a guy called Boris Johnson.
0:03:27 > 0:03:29It is now a man called Sadiq Khan.
0:03:29 > 0:03:32He is from the Labour Party, so a different party from the one
0:03:32 > 0:03:37that's in charge all over the country in Government.
0:03:37 > 0:03:41His dad used to be a bus driver and it is the first time in a big,
0:03:41 > 0:03:45rich western country that the mayor has been a Muslim.
0:03:45 > 0:03:48Footy news now and newly crowned champions Leicester take on Everton
0:03:48 > 0:03:50later today with the Foxes being presented with the Premier
0:03:50 > 0:03:51League trophy after the match.
0:03:51 > 0:03:53That will be a celebration not to be missed.
0:03:53 > 0:03:58The bottom five are all in action too with Norwich, Newcastle
0:03:58 > 0:04:00and Sunderland, who host Chelsea at the Stadium of Light,
0:04:00 > 0:04:08all desperate to pick up some valuable points.
0:04:08 > 0:04:10It's about performing to the level that you need to,
0:04:10 > 0:04:12because time is running out, games are running out
0:04:12 > 0:04:15and we all know what we have to try and do.
0:04:15 > 0:04:17There is no margin for error any more.
0:04:17 > 0:04:20We'll either be able to cope mentally or we won't.
0:04:20 > 0:04:27If we're able to God mentally, we will
0:04:27 > 0:04:29If we're able to cope mentally, we will
0:04:29 > 0:04:31be very close to staying up, I believe.
0:04:31 > 0:04:32Very, very close.
0:04:32 > 0:04:33In Spain, Britain's top tennis star Andy Murray
0:04:33 > 0:04:36is through to the semifinals of the Madrid open.
0:04:36 > 0:04:38The defending champ beat Tomas Berdych 6-3, 6-2
0:04:38 > 0:04:41to record his first ever win over the Czech on a clay court.
0:04:41 > 0:04:43The world number two will now face nine-time French Open champion
0:04:43 > 0:04:45Rafael Nadal in the last four.
0:04:45 > 0:04:55Now, it wouldn't be Newsround without a quick round-up of today's
0:04:57 > 0:04:59top animal stories, would it?
0:04:59 > 0:05:02Including this very cute baby
0:05:02 > 0:05:03dolphin.
0:05:03 > 0:05:05The two-week-old calf is a Pacific white-sided dolphin
0:05:05 > 0:05:08which has been born in the USA at an aquarium in chicago.
0:05:08 > 0:05:10Oh, and in case you're wondering, it's a boy!
0:05:10 > 0:05:14Now if you thought these looked like LED-lit pigeons,
0:05:14 > 0:05:15well, you'd be right!
0:05:15 > 0:05:19It's part of an art exhibition in new york city.
0:05:19 > 0:05:22The massive flock took off and circled for 30 minutes over
0:05:22 > 0:05:25the deck of their temporary home on an old US Navy ship,
0:05:25 > 0:05:28in a dockyard where military carrier pigeons were once trained.
0:05:28 > 0:05:31And staying in the US, these elephants, previously used
0:05:31 > 0:05:35in circus shows but have since been rescued, are getting used
0:05:35 > 0:05:38to their new home now that they'll no longer be used in performances -
0:05:38 > 0:05:43and don't they love it?
0:05:43 > 0:05:45Head online for more of the day's stories including how scientists
0:05:45 > 0:05:48are using modelling clay to find out more about a strange
0:05:48 > 0:05:49new underwater dinosaur.
