Israel Seals Gaza Border Crossings

Israel's Defense Ministry says it has has sealed the country's border crossings into the Gaza Strip in response to rocket fire.

Officials say Palestinian militants fired a rocket toward southern Israel on Monday, however no casualties or damage were reported.

It is unclear if or when the borders will reopen.

Israel allowed several truckloads of humanitarian aid and other supplies into the area on Monday.

International concern about the shortage of basic goods in Gaza has mounted since Israel tightened its blockade of the Palestinian territory November 4. Israeli officials say the action was prompted by an earlier surge in rocket and mortar attacks.
