Israeli troops advanced toward Gaza City on Thursday, as the Palestinian death toll rose above 9,000. With no end in sight after weeks of heavy fighting, U.S. and Arab mediators intensified efforts to ease Israel's siege of the Hamas-ruled enclave and called for at least a brief halt to the hostilities in order to aid civilians.

U.S. President Joe Biden suggested a humanitarian "pause" the day before, as an apparent agreement among the U.S., Egypt, Israel and Qatar, which mediates with Hamas, allowed hundreds of Palestinians with foreign passports and dozens of wounded to leave Gaza for the first time. Dozens more left on Thursday.

Over the past five days, Israeli ground troops have pushed deeper and deeper into Gaza in their war against Hamas, launched in response to a bloody Oct. 7 cross-border raid by the Islamic militant group.

A growing array of units, including naval, air and ground forces, have joined the effort. The army says it has killed scores of militants and damaged Hamas' strategic tunnel network. Soldiers have taken over abandoned Palestinian homes to stake out positions.

At least four Palestinians were killed during Israeli raids in the occupied West Bank, Palestinian health officials said Wednesday, as violence there continued in tandem with the Israel-Hamas war in Gaza.

Three people were killed during a raid in the northern city of Jenin, while another was shot dead in Tulkarem, also in the north, the Ramallah-based health ministry said.

The Hamas-run government in Gaza says Israeli airstrikes have hit apartment blocks in a refugee camp near Gaza City for a second day in a row, causing many deaths and injuries.

The toll from Wednesday’s strikes on Jabalia was not immediately known. Al-Jazeera television, which is still reporting from northern Gaza, aired videos of devastation and of several wounded people, including children, being brought to a nearby hospital.

Hamas said Wednesday that seven hostages, including three foreign passport holders, were killed in Israel's bombing of Gaza's largest refugee camp.

Dozens of bodies were seen on Tuesday at the Jabalia camp where Israel said it killed a Hamas military commander in a strike on a tunnel complex.

Bolivia's government severed diplomatic relations with Israel on Tuesday, accusing it of carrying out "crimes against humanity" in Gaza, and Chile and Colombia recalled their ambassadors to Israel as they criticized the Israeli military offensive against Hamas militants.

Bolivian officials cited the number of Palestinian casualties in Gaza that have resulted from the latest Israel-Hamas war, but made no mention of the Hamas attack on Israel at the start of the conflict.

Palestinians reported another widespread outage of internet and phone service in Gaza early Wednesday, hours after Israeli airstrikes leveled apartment buildings near Gaza City and as ground troops battled Hamas militants inside the besieged territory.

Humanitarian aid agencies have warned that such blackouts severely disrupt their work in an already dire situation in Gaza, where more than half of the population of 2.3 million Palestinians has been displaced and basic supplies are running low more than three weeks into the war triggered by Hamas' bloody Oct. 7 rampage into southern Israel.

Scores of foreign passport holders trapped in Gaza started leaving the war-torn territory on Wednesday as the Rafah crossing to Egypt opened for the first time since the October 7 Hamas attacks, AFP correspondents reported.

Convoys of desperately needed aid have passed between Egypt and Gaza but no people have been allowed to cross. Some 400 foreigners and dual nationals along with some 90 sick and wounded were expected to leave on Wednesday.

Cyprus is working out with partners in the European Union and the Middle East the logistics to establish a sea corridor to deliver a stream of vital humanitarian aid to Gaza from the island's main port of Limassol once the situation on the ground permits it, authorities said Tuesday.

A senior government official — who spoke on condition of anonymity because he's not authorized to publicly discuss details of the proposal — said Israeli Prime Minister Benjamin Netanyahu "wasn't opposed" to the idea pitched by Cypriot President Nikos Christodoulides last week.

Iran said on Tuesday it was "natural" for Tehran-backed groups to attack Israel in light of its war on Hamas, warning of a wider spillover if no ceasefire is reached.
