Fatah-led Palestinian Authority security forces arrested 15 Hamas loyalists on Sunday in the Samarian city of Tulkarem.

Among those arrested were two Hamas officials. The raid came in response to a roundup over the weekend in which Hamas arrested at least 160 Fatah loyalists in Gaza following a beachside explosion in which five Hamas operatives and a six-year-old girl were killed. Hamas blamed Fatah for the blast.
