Residents in Gaza said they had received renewed warnings from Israel's military to move from the north to the south of the strip, adding they could be identified as sympathisers with a "terrorist organisation" if they didn't move.
The message was delivered in leaflets marked with the Israel Defence Forces name and logo from Saturday and sent to people via mobile phone audio messages across the Gaza Strip.
"Urgent warning, to residents of Gaza. Your presence north of Wadi Gaza puts your life in danger. Whoever chooses not to leave north Gaza to the south of Wadi Gaza might be identified as an accomplice in a terrorist organisation," the leaflet said.
Just hours after the Israeli army spokesman Admiral Daniel Hagari called on Gaza residents to move south, a mosque in Jenin was hit during night raids.
In a media briefing, Hajari said they will "continue the attack in the Gaza City area and increase the attacks".
According to Palestinian media, at least 11 Palestinians were killed in an Israeli raid on the city of Khan Yunis in the southern Gaza Strip.
Palestinian medics said that Israeli aircraft also bombed the Jenin refugee camp in the occupied West Bank early on Sunday morning, killing two and wounding a number of others.
It comes a day after the Gaza Strip received the first humanitarian aid convoy since the outbreak of the war.
The United Nations said that the convoy of 20 trucks carrying life-saving supplies will be received by the Palestinian Red Crescent.
But the United Nations Office for Humanitarian Affairs said that the volume of goods that entered yesterday, Saturday, is equivalent to about 4 percent of the average daily imports that entered Gaza before the crisis, and represents only a small part of what is needed after 13 days of siege of the Strip, in which 2.3 million people live.
