Israel: Bus blast in Bulgaria caused by bomb

SOFIA, Bulgaria (AP) -- Israel's Foreign Minister says the deadly bus explosion in Bulgaria that has killed at least six people was caused by a bomb placed on the vehicle.

Avigdor Lieberman says he was briefed by his Bulgarian counterpart Wednesday evening. He said seven people died, but Bulgarian authorities have placed the death toll at six.

At least 32 people were wounded in the blast, which Israeli Prime Minister Benjamin Netanyahu called "an Iranian terror attack."
