Israel and Hamas are once again struggling to reach a ceasefire that could wind down the 15-month war in Gaza and bring home dozens of Israelis held hostage.

Israel has vowed to catch the perpetrators after gunmen killed three people and wounded seven others in an attack on a bus carrying Israelis in the West Bank. It comes as outgoing U.S. Secretary of State Antony Blinken says he maintains hope that a ceasefire deal between Israel and Hamas could be reached in the near future.

A renewed push is underway to reach a ceasefire in the 15-month war and return Israeli hostages before Donald Trump takes office on Jan. 20.

The White House is hoping to see a ceasefire agreement between Israel and Hamas concluded before Joe Biden leaves office, Antony Blinken has said.

Israel said Monday that Hamas had yet to clarify whether 34 hostages it said it was ready to free were dead or alive, throwing doubt on the group's assertion that it needed time to ascertain their fate.
