The Israeli military says Palestinian militants in the Gaza Strip have fired a rocket into southern Israel, amid a sharp increase in tensions.
A statement said sirens were triggered in Israeli communities near the border but the rocket landed in open countryside and no-one was hurt.
Earlier, six Palestinians were shot dead near the border fence with Gaza. There has been a spate of attacks and confrontations between Palestinians and troops in recent days. The military statement said the rocket was believed to have landed in a field not far from the border early on Saturday.
Gun and knife attacks by Palestinians have left four Israelis dead and many wounded since last weekend, while at least three Palestinians have been killed during clashes with security forces in the West Bank and East Jerusalem.
Ismail Haniyeh, the leader of Hamas which runs Gaza, said a new intifada – or uprising – was under way, although the BBC’s Yolande Knell in Jerusalem says the scale of violence does not yet amount to that.
