The Daesh terrorist group has claimed responsibility for a rocket that was reportedly fired on Monday into southern Israel from Egypt's volatile Sinai Peninsula.
"The fatal terrorist attacks which took place today reflect once again the terror capability of the Islamic State", the Israeli government anti-terror bureau said in a statement.
A rocket fired from Egypt's Sinai crashed into Israel Monday, in an attack claimed by the Islamic State militant group, as authorities closed a border crossing over security threats, officials said.

Intelligence Minister Yisrael Katz said in a statement there was intel regarding a potential "terror attack" against tourists in the Sinai peninsula. The closure came following an alert by the National Security Council Counter-Terrorism Bureau of concrete information of a planned attack targeting Israeli citizens. Officials said that Israelis who were already in Egypt would be allowed to return through the border crossing.

It adds that with the Islamic State group losing ground in Iraq and Syria, there is renewed "motivation to carry out terror attacks in different arenas at this time".
Israel's anti-terrorism office issued the recommendation on Sunday, citing what it said was a heightened alert level and twin church attacks that killed dozens of Christian worshippers.
