US President, Joe Biden, has voiced his support for a ceasefire after eight days of violence between Israel and Palestinian militants in Gaza.
A BBC report says Biden told Israeli Prime Minister, Benjamin Netanyahu, that the US was working with Egypt and other countries on halting hostilities.
But the US again blocked a UN Security Council statement calling for a cessation of violence.
The conflict is now in its second week, with little sign of ending.
At least 212 people, including 61 children, have died in Gaza, and 10, including two children, in Israel.
Israel says most of those killed in Gaza are militants and that any civilian deaths are unintentional.
But Hamas, the militant group that runs the territory, disputes this.
According to a White House statement, Biden “encouraged Israel to make every effort to ensure the protection of innocent civilians”.
“The two leaders discussed progress in Israel’s military operations against Hamas and other terrorist groups in Gaza”, it added.
President Biden “expressed his support for a ceasefire and discussed US engagement with Egypt and other partners towards that end”, it said.
The violence has prompted increasing concern internationally.
World leaders and humanitarian organisations have called for measures to prevent the deaths of residents and the chaos wrought by the destruction of buildings and infrastructure.
The US 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.
”Our calculation at this point is that having those conversations behind the scenes … is the most constructive approach we can take”, White House spokeswoman Jen Psaki told reporters.
Biden Follows Familiar Pattern, Analysis by Barbara Plett-Usher, State Department Correspondent
Joe Biden is a traditional pro-Israel Democrat. That’s different from Donald Trump who actually changed US policy to adopt Israel’s positions in its conflict with the Arabs. Biden has quietly begun to reverse some, although not all, of that.
But when it comes to air wars with Palestinian militants, he is following a familiar pattern. All US administrations strongly support Israel’s right to defend itself against rocket fire.Analysts say in the initial phase they generally refrain from public criticism of Israeli air strikes, including at the United Nations, apparently allowing a window of time for Israel to take out militant leaders and infrastructure.
However, if the conflict goes on and civilian deaths mount, sometimes they become more critical and start pressing Israel to wind down its military campaign.
In this case Hamas’ firepower has been more sustained and intense than before. But President Biden has now publicly expressed support for a ceasefire in his call with the Israeli Prime Minister Benjamin Netanyahu, and discussed with him “progress in Israel’s military operations against Hamas.”
So perhaps this is the beginning of new phase.
The United Nations has also expressed concerns about the damage to infrastructure in the already impoverished Gaza Strip, home to two million people. It said that 40 schools and four hospitals had been “completely or partially destroyed” in recent days. It also warned that fuel supplies there were running out, threatening basic services.
The World Health Organization’s emergencies chief, Dr Mike Ryan, said all attacks on healthcare needed to stop immediately.
The outbreak of violence began after weeks of rising Israeli-Palestinian tension in occupied East Jerusalem that culminated in clashes at a holy site revered by both Muslims and Jews. Hamas, which controls Gaza, began firing rockets after warning Israel to withdraw from the site, triggering retaliatory air strikes.
