Two bombs exploded at bus stops on Jerusalem’s outskirts on Wednesday, killing a 16-year-old boy and wounding at least 14 other people, in what appeared to be an attack by Palestinian militants, Israeli authorities said.

Police blamed the initial blast, during morning rush hour, on an improvised bomb at a bus station near the city exit. The second — about 30 minutes later — hit a bus stop near a settlement east of the city. “There has not been such a coordinated attack in Jerusalem for many years,” police spokesman Eli Levi told Israeli Army Radio. The devices were hidden in bags, packed with nails and appeared to have been detonated remotely by mobile phone, Israeli public broadcaster Kan Radio said.

Security camera footage showed the moment of the first explosion with a sudden cloud of smoke billowing from the bus stop. Television showed debris strewn around the site.

Ambulance services said 12 people were taken to hospital from the first blast and three were wounded in the second. A 16-year-old Canadian-Israeli national died in the hospital. The UN, the EU and US condemned the attacks. “Terrorism is a dead-end that accomplishes absolutely nothing,” the US embassy said.
