WASHINGTON (AP) — The White House says the apparent abduction of an Israeli soldier would be an "absolutely outrageous" action by Hamas.

Tony Blinken is deputy national security adviser. Blinken says the U.S. strongly condemns the alleged abduction. He says that if the soldier has been kidnapped, he must be released.

The Israeli military said Friday that one of its soldiers was "feared" abducted, without providing further details. The report came as a cease-fire with Hamas collapsed just hours after it took effect.

Thirty-five Palestinians were also killed Friday by Israeli shelling.

Blinken said Secretary of State John Kerry was speaking to Israeli Prime Minister Benjamin Netanyahu about the unraveling cease-fire Friday morning. His comments came in interview on MSNBC.
