ISIS threatens to topple Hamas in Gaza

Islamic State insurgents threatened to turn the Gaza Strip into another of their Middle East fiefdoms, accusing Hamas, the organization that rules the Palestinian territory, of being insufficiently stringent about religious enforcement.

The video statement, issued from an Islamic State stronghold in Syria, was a rare public challenge to Hamas, which has been cracking down on jihadis in Gaza who oppose its truces with Israel and reconciliation with the U.S.-backed rival Palestinian faction Fatah.
