JERUSALEM – Israel says it is keeping Gaza's border crossings closed in retaliation for a rocket attack.

Israeli army spokesman Peter Lerner says all cargo passages remained shut Friday morning. He says the decision came Thursday after Palestinians fired a rocket toward Israel. No injuries were reported.

The rockets and closure are violations of a June 19 cease-fire. Since then, the army says 11 rockets and mortars have been fired toward Israel. The cargo crossings have been closed for a total of seven days, including Friday.

Israel imposed a blockade on the territory of 1.4 million Palestinians a year ago, after Hamas overran Gaza. Only food and medicine have been allowed in and Palestinians report severe shortages in everything from gasoline to cement and shoes.
