GAZA CITY, Gaza Strip (AP) — The Palestinian militant Hamas group has convicted a Gaza man on charges of spying for Israel and sentenced him to death.

Hamas announced the move Thursday, the latest in a secretive campaign to rid Gaza of alleged Israeli collaborators.

The campaign has underscored Hamas' deep fears about being penetrated by agents of the Jewish state.

Hamas says its military court sentenced Omar Kawari to death by a firing squad. It provided no other details.

In May, Hamas executed three Gazans, convicted as collaborators. Eleven others have also been sentenced to death.

Gazans support crackdowns on accused collaborators but Hamas' latest campaign has also sparked panic because many prominent Gaza residents are believed to have been arrested.
