Hamas and Israel were in negotiations in December to reach a ceasefire deal, but while reports at the time appeared to show progress in striking a deal, the Palestinian group accused Israeli negotiators of putting forward "new conditions" that delayed coming to an agreement.

Israeli airstrikes killed at least 50 people, including several children, across the Gaza Strip on Thursday, hitting Hamas security officers and an Israeli-declared humanitarian zone.

Hamas said a new round of indirect talks on a Gaza ceasefire resumed in Qatar's Doha on Friday, stressing the group's seriousness in seeking to reach a deal as soon as possible, senior Hamas official Basem Naim said.
