The Austrian authority has found bodies of dozens of migrants in an abandoned lorry near the Hungarian border. Police said there appeared to be between 20 and 50 bodies in the vehicle. Conditions in the lorry were such that it was not immediately possible to verify the number of bodies. Bettery Ben reports from Vienna.

Police told the BBC they initially thought the vehicle had been involved in an accident. They then noticed blood seeping out at the back of the lorry. When they opened it up, they then discovered dozens of dead bodies in an advance state of decomposition. Police in white forensic suits spent several hours combing the area for evidence. A police hunt is on for the driver both in Austria and Hungary.

The bodies were discovered as the leaders of Germany, Austria and six states in the western Balkans which lie on the migration mood were meeting in Vienna. The German Chancellor Angela Merkel said all had been shocked by the news. She described it as a warning to all of Europe and added that Europe had to share responsibility to help those most in need. "Drawing from our own historic experiences, it's important to give shelter to people whose lives are in danger wherever they may come from, in areas of war and crisis. Everybody knows for the situation in Syria is life. And everybody knows about the burdens Syria's neighboring countries are shouldering. So it's up to Europe as a rich continent to step in and help."

Two Iraqi army generals have been killed in a suicide car bombing at the command military headquarters, north of the city of Ramadi. The Islamic State group said it carried out the attack. Our Middle East editor Jondonson reports.

The suicide car bomb is a favored weapon of the IS militants and on rushing vehicle packed to explosives is hard to defend against. These latest attacks killed two very senior army commanders. They died near the strategically important city of Ramadi which IS captured in May. At the time, the government said it would quickly retake the city, perhaps, even within days. But in fact, three months on the army's counter offense has made very little progress.

A two-day ceasefire, agreed between the Syrian government and rebel forces, has reportedly begun in two places. One is the rebel-held town of Zabadani, near the Lebanese border. The other location included in the truce is a pair of government-held villages in Northern Syria. The truce will enable the delivery of aid.
