Israel has resumed attacks on Gaza after Hamas militants ignored calls for a ceasefire and launched rockets into Israel. Hamas says it was not consulted about the truce plans put forward by Egypt.
Palestinian officials say at least 192 people have been killed by Israeli air strikes since Israel's 'Operation Protective Edge' began last week.
Israel says Hamas fired more than 30 rockets at towns across the border. After a brief ceasefire, Israel responded to the Hamas attacks with new airstrikes inside Gaza.
The Israeli Prime Minister Benjamin Netanyahu says he is willing to escalate the operation if necessary.
While the plan was welcomed by US President Barack Obama and the Arab League, Hamas' armed wing Ezzedine al-Qassam Brigades said it amounted to a surrender.
The group said in a statement "No official or unofficial side has approached us about the cease-fire talked about in the media...(but) if the contents of this proposal are true, it is a surrender and we reject it outright. Our battle with the enemy will intensify".
A senior Hamas official, Sami Abu Zuhri, told AP news agency "This proposal is not acceptable".
Palestinian President Mahmoud Abbas, who heads the West Bank-based Palestinian Authority, welcomed the Egyptian initiative and earlier urged both sides to stop fighting.
Speaking at an Iftar dinner marking the Muslim Holy month of Ramadan in the White House on Monday, Mr. Obama described the deaths of Palestinians as "a tragedy" but reiterated that Israel had the right to defend itself from Hamas rocket attacks.
Human rights groups say more than 75% of the dead have been non-combatants and the United Nations agency for Palestinian refugees says more than a quarter of them have been children.
The raids have prompted some 17,000 people to flee their homes, particularly in northern Gaza, with many taking refuge in UN schools.
So far, no Israelis have been killed. Four have been seriously wounded.
Senior United Nations humanitarian officials on a visit to the area yesterday called for an immediate return to calm and a ceasefire to avoid further loss of life.
"We must once again remind all parties that they must strictly adhere to international humanitarian law" the UN Humanitarian Coordinator in the occupied Palestinian territory, James Rawley, said alongside the Commissioner-General of the UN Relief and Works Agency for Palestine Refugees in the Near East (UNRWA), Pierre Krähenbühl.
He noted the need to fully respect the principles of distinction between civilians and combatants, proportionality, and taking precautions to avoid civilian casualties.
"Never will even the most impressive television footage properly capture the depth of fear and despair felt in the homes and hearts of Gazans who are yet again facing death, devastation and displacement" he said.
The UN agency has now declared an emergency for operations in all five of its areas in Gaza, with approximately 17,000 refugees seeking refuge in its 20 schools.
At least 33 children were killed in Gaza in recent days, the UN Children’s Fund (UNICEF) reported Sunday - highlighting the negative impact violence has on children both physically and psychologically. "Too often children who witness such violence, and come to view it as 'normal', are likely to repeat it themselves in later life" he added.
