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.

The two sides have agreed on a list of prisoners Israel will release. However, Israel says it's waiting for a list of surviving hostages from Hamas.
