Casualties in Jerusalem bus blast, cause unclear: Israeli police

An explosion aboard a bus in Jerusalem caused around 20 casualties on April 18, Israeli media said, and police said it may have been a militant attack or the result of a fire from other causes. 

Television images showed smoke billowing from two burned-out buses, one of which apparently set fire to the other, on Derech Hebron, an area in southwest Jerusalem close to the boundary with the Israeli-occupied West Bank. Smoke billowed over the horizon. 

It was not immediately clear if the casualties included fatalities. Israel's Magen David Adom ambulances service said it had taken 10 wounded people to hospitals and that others remained at the site of the blast. 

Attacks on Israeli buses by suicide bombers were a hallmark of the Palestinian uprising in 2000-2005 but have been rare since. 

An Israeli police spokeswoman initially said there were indications that the incident on April 18 was a militant attack, but in an updated statement said it may have begun when an empty bus caught fire, ignited another bus that had passengers aboard.First migrants arrive on Turkey's western coast under EU dealIstanbul's Be?ikta? returns to nest at brand new Vodafone ArenaErdo?an hosts Islamic Summit leaders on presidential yachtHalfeti - A town of mesmerizing beautyExhibition shows Istanbul through eyes of children Secret weapons of Turkish army: locally produced rocket launchers, missile systemsThe bugs of Ankara: The weirdest scenes that anyone can run into in Turkish capitalA bird's eye view tour of Turkey's eastern provinces of Van and HakkariTurkish man with four wives has his 32nd childTurkish police raid Koza ?pek's media HQ in Istanbul amid protestsTurkey celebrates Republic Day against backdrop of political turbulenceLocal authorities in Ad...
