Quds city, (JERUSALEM), July 01, SPA -- Israel snapped shut its cargo crossings with the Gaza Strip on Tuesday, accusing firing of a rocket from Gaza at southern Israel in violation of a shaky truce. Gaza's Hamas rulers denied a rocket was fired on Monday evening, and accused Israel of looking for excuses to shirk its commitment under the cease-fire agreement to ease its blockade of impoverished Gaza, the Associated Press reported. «The closing of the border today is unjustified and another indication that the Israeli occupation is maneuvering and trying to dodge the conditions of the calm understanding, » Hamas spokesman Sami Abu Zuhri said. The Israeli military said its radar detected a rocket launched from Gaza that struck near the communal farm of Mefalsim. But it said actual rocket fragments were not located, and local security officials were searching for them Tuesday morning.
