Hamas has projected a united front since its Oct. 7 attack sparked war with Israel, but experts say divisions within the Palestinian movement have weighed on efforts toward a cease-fire.

Meanwhile the group's leader in the Gaza Strip, Yahya Sinwar, is in hiding after Israel vowed to pursue the presumed brains behind the October attack to the death.
