The Israeli military says a rocket fired from the Gaza Strip has landed in southern Israel, further straining the fragile cease-fire between Israel and the Palestinian militant group Hamas.

Israeli officials did not report any injuries or damage from the rocket. No one has claimed responsibility for Monday's incident.

Hamas has warned it will take action against anyone who breaks the truce.

On Sunday, Israel re-opened a border crossing with Gaza to allow about 80 truckloads of commercial goods into the Palestinian territory.

Israel closed the crossings after an Islamic Jihad rocket attack last week. The group said the attack was revenge for Israel's killing of one of its commanders in the West Bank.

The West Bank is not included in a cease-fire agreement between Israel and Hamas leaders in the Gaza Strip.
