Your wrap of the world stories that broke overnight.

1. More than 110,000 refugees and migrants have arrived in Europe this year - triple the rate of the first half of last year. Belgium has tightened its border with France - deploying 290 police - over fears of a migrant influx. A French court is considering the legality of plans to evict migrants from the Jungle camp in Calais.

2. A major incident has occurred at the Didcot power station in Oxfordshire about 110km west of London. The BBC says casualties are feared after an explosion. The coal-fired plant ceased generating in 2013.

3. Mars has launched a recall of Dutch-made chocolate bars from 55 countries, mainly in Europe, after plastic pieces were found in a Snickers bar in Germany in January. The bar was traced to a factory in Veghel, the Netherlands.

4. A 16-year-old Swedish girl has been rescued from Isis (Islamic State) near Mosul in Iraq, Kurdish officials say. The girl from Boras was "misled by an Isis member in Sweden to travel to Syria and Iraq," a Kurdish statement says, and will be transferred to Swedish authorities to return home. She was 15 and pregnant when she ran away with her boyfriend last May.

5. Scottish nurse Pauline Cafferkey has been flown to a London hospital after being admitted to a hospital in Glasgow for a third time since contracting Ebola. She worked in Sierra Leone in 2014.

6. US President Barack Obama has made a renewed push to close the Guantanamo Bay prison, presenting Congress with a plan. The White House wants to transfer the remaining 91 detainees to their home countries or US military or civilian jails. It costs US$445 million to run the prison each year. Obama promised to close it in 2009 but Republicans in Congress are against the detainees being on US soil.

7. A Swedish doctor has been sentenced to 10 years in jail after being found guilty of kidnapping a woman and keeping her in a bunker for six days. Martin Peter Trenneborg had admitted kidnapping but denied rape and was acquitted of that charge. Dubbed Sweden's Fritzl, he had planned to hold his victim captive in the bunker for years.

8. The Egyptian family of a 3-year-old boy sentenced to life in prison last week say they are relieved after receiving assurances from officials that neither the boy nor his father will be arrested. In a bizarre case of mistaken identity, Ahmed Mansour Qorany Sharara - along with 115 others - was found guilty of killing three people during a 2014 protest when he was 16 months old. When police first tried to arrest Ahmed and realised he was a toddler they took his father instead. After four months in detention the father spent 18 months on the run. Officials say they are seeking a 16-year-old instead.
