GAZA CITY - Israeli strikes in Gaza killed more than 200 people in 24 hours, Hamas-controlled authorities said, as the United States again pressed its ally to do more to protect civilians.
Despite growing calls for restraint and for more aid to reach war-stricken Palestinians, Israel showed little sign of modulating its 11-week-old "Operation Swords of Iron" -- which aims to rout Hamas.
Fighting is now centred on Gaza City and the southern city of Khan Yunis, both considered strongholds of the Palestinian militant group that carried out bloody October 7 raids into Israel.
Outside a morgue at the city's Nasser Hospital, grieving relatives prayed, wept and stared vacantly as they tried to process incalculable loss.
Hamas authorities said the death toll from this war has now surged beyond 20,000.
Israel denies directly targeting civilians and says the war against Hamas is vital to ensure the October raids on farms, villages and kibbutzim that killed an estimated 1,140 people can never be repeated.
In Washington, President Joe Biden said he had another "long talk" with Israel's hawkish prime minister, Benjamin Netanyahu.
The White House said the discussion focused on the "objectives and phasing" of Israel's military operation, as well as "the critical need to protect the civilian population including those supporting the humanitarian aid operations".
Israeli officials gave a terse readout of the call, saying "the Prime Minister made it clear that Israel would continue the war until all of its goals have been achieved".
A total of 144 Israeli troops have been killed since the ground offensive began almost a month ago.
