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 says Hamas has not provided any information about the status of those 34 hostages, dampening any notion that the endorsement is a step toward a deal to stop the war.

Hamas has approved a list of 34 Israeli hostages to be exchanged in a possible ceasefire deal, Reuters reported, citing a Hamas official. The Israeli government denied receiving a list of hostages from Hamas, adding that the names published in the media are from an older list that Israel had presented to mediators.

The Israeli military launched a wave of raids across the occupied West Bank overnight and into Tuesday, killing at least three Palestinians it said were militants a day after a deadly shooting attack.
