Daily US Times: President Joe Biden has voiced his support for a ceasefire after eight days of intensified violence between Israel and Palestinian militants in Gaza.
The US President told Prime Minister Benjamin Netanyahu of Israel that the US was working with Egypt and other countries on halting hostilities.
But the United States again blocked a UN Security Council statement calling for a cessation of violence.
The conflict is enters its second week, with little sign of ceasefire.
At least 212 people, including 61 children, have died in Gaza by Israeli bombing, and 10, including two children, in Israel.
Israeli military says most of those killed in Gaza are militants and that any civilian deaths are unintentional.
But Hamas, the militant group that rules the territory, disputes this.
Mr Biden “encouraged Israel to make every effort to ensure the protection of innocent civilians”, according to a White House statement.
The statement added: “The two leaders discussed progress in Israel’s military operations against Hamas and other terrorist groups in Gaza.”
President Joe Biden “expressed his support for a ceasefire and discussed US engagement with Egypt and other partners towards that end”, the statement said.
The violence has prompted increasing concern across the world.
Humanitarian organisations and world leaders have called for measures to prevent the deaths of residents and the chaos wrought by the destruction of buildings and infrastructure.
The United States has – for the third time – blocked efforts at the UN Security Council to issue a statement calling on Israel to stop its military offensive, stressing instead its own diplomatic efforts.
