Hamas has announced the names of the next four hostages it will release this weekend as part of a ceasefire deal with Israel that has halted fighting in Gaza for at least six weeks.

Israeli Prime Minister Benjamin Netanyahu’s office said Thursday his Cabinet won’t meet to approve the agreement for a ceasefire in the Gaza Strip and the release of dozens of hostages until Hamas backs down, accusing the group of reneging on parts of the agreement in an attempt to gain further concessions.
