The Israeli military says Palestinian militants have launched a rocket from Gaza, violating an unwritten cease-fire that ended Israel's Gaza offensive.
The military says the rocket hit near an Israeli communal farm, causing no damage or injuries.
Friday's rocket fire followed an incident late on Thursday on the Gaza-Israel border in which Israeli forces shot and killed a Palestinian who the military said was armed with a grenade. Israel unilaterally halted its devastating Gaza operation on Jan 18, and Hamas followed with an announcement that it would hold its fire.
Militants have sporadically fired rockets into Israel since, and killed one soldier in a border bombing attack. Israeli troops have killed three Palestinians who Gaza officials identified as farmers in border shootings.
