Two explosions at bus stops on Jerusalem's outskirts killed one person and wounded at least 14 others on Wednesday, health officials said, in what Israeli police said appeared to be an attack by Palestinian militants.

Lisa Stadelbauer, the Liberal government's ambassador to Israel, said the deceased was a "young Canadian," confirming earlier media reports from multiple outlets in Israel.

"Heartbroken to confirm that a young Canadian lost his life in this morning's reprehensible terror attack in Jerusalem," said Stadelbauer on Twitter. "Our sincere condolences to his family and friends, and to others wounded in this attack. Canada continues to condemn all forms of terror."

Benjamin Netanyahu of the Likud Party identified the victim in a tweet as Aryeh Shechoupek, although some outlets spelled the surname differently.

He has been described in the media as being 15 or 16 years old.

Israel's ambulance service said 12 people had been taken to hospital from the first blast and three people were wounded in the second explosion. One of the wounded, a teenager, died in hospital, the Shaare Zedek Medical Center said.

The initial blast occurred from an explosive device planted at a bus station near a city exit. The second — about 30 minutes later — hit a bus stop in the vicinity of an urban settlement in the east of the city.

Police spokesperson Eli Levi told Israeli Army Radio the first blast was caused by a powerful explosive device.

"There has not been such a co-ordinated attack in Jerusalem for many years," Levi said.

The same outlet reported that the explosive devices were hidden in bags and at least one of them contained nails to maximize the impact.

"It was a crazy explosion. There is damage everywhere here," Yosef Haim Gabay, a medic who was at the scene when the first blast occurred, said. "I saw people with wounds bleeding all over the place."

While Palestinians have carried out stabbings, car rammings and shootings in recent years, bombing attacks have become rarer since the end of a Palestinian uprising nearly two decades ago.

Bus bombings more frequent in years past

Security camera footage aired by N12 news 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, which was cordoned off by emergency services.

The United Nations, the European Union and the United States condemned the attacks.

"Terrorism is a dead-end that accomplishes absolutely nothing," the U.S. Embassy said on Twitter.

The explosions, which carry echoes of the bus bombings that were a hallmark of the Palestinian revolt of 2000-2005, follow months of tension in the occupied West Bank after the Israeli military launched a crackdown in the wake of a series of deadly attacks in Israel.

In Gaza, a spokesperson for the Palestinian militant group Hamas praised the Jerusalem explosions but stopped short of claiming responsibility.
