A 15-year-old boy has been killed and 14 other people have been wounded in two suspected bomb attacks at bus stops in Jerusalem, Israeli police say.

The explosions happened at two busy areas on the outskirts of the city as people were heading to work.

The teenager who died was an Israeli-Canadian Jewish seminary student named Aryeh Schupak. Israel's prime minister said it was an attack that was "different from what we have seen in recent years".

No group has so far said it was behind the blasts. However, the Palestinian militant groups Hamas and Islamic Jihad both praised the perpetrators of what they referred to as the "operation".

The first explosion happened in Givat Shaul, close to the main entrance to Jerusalem, just after 07:00 (05:00 GMT) on Wednesday.

Israeli medics said the blast wounded 12 people, including the teenage boy who died later at the Shaare Zedek Medical Center.

About 30 minutes later, there was a second blast in Ramot Junction, another entrance to the city. It left three people with minor injuries.

Debris covered the pavement where the first explosion occurred. The area was cordoned off by masked Israeli security personnel, and bits of a severely broken bicycle were placed in forensics bags.
