JERUSALEM (AP) _ An explosion, apparently detonated by a suicide bomber, went off Sunday at an office for paramedics in the Jewish settlement of Efrat in the West Bank, medics and TV reports said.

Four people were wounded, including one who was in serious condition, medics said. One of the wounded apparently was a paramedic in training.

The explosion went off less than two hours after a suicide bomber blew himself up in a crowded restaurant in the port city of Haifa, killing himself and at least 12 other people.
