JERUSALEM — A terror group abducted three teens, including an American, who disappeared in the West Bank, Israel’s prime minister said Saturday, as soldiers searched the territory to find them.

Prime Minister Benjamin Netanyahu again blamed the Palestinian Authority for the Thursday night disappearance of the teens. Palestinian officials say they are assisting Israeli forces, who poured over surveillance footage Saturday and arrested more than a dozen Palestinians.

There have been at least three claims of responsibility for the abduction, though none could be immediately verified.

Netanyahu made a televised address Saturday night after meeting with top security officials, saying Israeli forces were conducting “intensive operations” to locate the teens and bring them home.

“Our children were kidnapped by a terror group,” he said. “There is no doubt about that.”

They were reportedly hitchhiking when they were abducted.
