A 16-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.
Israeli media said the teenager who died was an Israeli-Canadian religious student named Aryeh Shtsupak.
Israel's internal security minister said at one scene that this was "an attack we haven't seen in a long time".
The atmosphere in the city feels volatile in a year of intensifying violence: Palestinian gun and knife attacks have targeted Israelis, and Israeli military raids have killed Palestinian gunmen and civilians in the occupied West Bank.
A return to the use of explosives in Jerusalem makes it one of the most significant attacks of its kind in 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".
