US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu will meet again on Tuesday evening to discuss Gaza, a day after they met for hours while officials conducted indirect negotiations on a US-brokered ceasefire.

Trump and Netanyahu dined together on Monday at the White House during the Israeli leader's third US visit since the president began his second term.

Netanyahu spent much of Tuesday at the US Capitol, telling reporters after a meeting with House of Representatives Speaker Mike Johnson that while he did not think Israel's campaign in the Palestinian enclave was done, negotiators are "certainly working" on a ceasefire.

He was due to meet in the afternoon with US Senate leaders before returning to the White House for another session with the Republican president.

The Gaza war erupted when Hamas attacked southern Israel in October 2023, killing around 1,200 people and taking 251 hostages, according to Israeli figures.

Some 50 hostages remain in Gaza, with 20 believed to be alive.

Israel's retaliatory war in Gaza has killed over 57,000 Palestinians, according to the enclave's health ministry.

Most of Gaza's population has been displaced by the war and nearly half a million people are facing famine within months, according to United Nations estimates. (Reuters)
