Israeli police say a rocket fired from Gaza has hit a house in southern Israel but caused no injuries.

Israel has kept its frontier with Gaza closed except for occasional shipments of essential humanitarian aid since a truce with Palestinian militants there started unraveling in early November in a series of cross-border rocket attacks and Israeli airstrikes.

Israel says the border crossings will stay closed until the rocket fire comes to a stop.

Police spokesman Micky Rosenfeld said Thursday's rocket attack damaged a house on a kibbutz, or collective farm.
