GAZA CITY, Gaza Strip – A leading Islamic cleric in the Gaza Strip has ruled it a sin to violate the recent cease-fire between Israel and the Hamas militant group that governs the Palestinian territory – according a religious legitimacy to the truce and giving the Gaza government strong backing to enforce it.

The fatwa, or religious edict, was issued late Saturday by Suleiman al-Daya, a cleric respected by both ultra-conservative Salafis and Hamas. Salafi groups oppose political accommodations with Israel.

"Honoring the truce, which was sponsored by our Egyptian brethren, is the duty of each and every one of us. Violating it shall constitute a sin," the fatwa read.
