Israeli forces killed at least 87 Palestinians in airstrikes in Gaza on Tuesday, local health authorities said, continuing to bombard the enclave despite mounting international pressure to halt military operations and allow unimpeded deliveries of aid.

Britain announced it was suspending trade talks with Israel and summoning its ambassador over "egregious policies" in the occupied West Bank and Gaza, while European Union foreign policy chief Kaja Kallas asked for a review of the EU-Israel trade deal, according to Dutch news agency ANP.

The conflict, now in its 20th month, has left Gaza in ruins and its population facing a worsening hunger crisis.

The Israeli military said its warplanes struck more than 100 locations in Gaza over the past day. In northern Gaza, targets included militants, a weapons storage site, a military structure used by Islamic Jihad, and underground infrastructure. In the south, the strikes targeted militants, military compounds and observation posts.

Israel's military chief Eyal Zamir said in a video statement from Gaza, "We will expand our operation, establish operational control over more territory, and clear and dismantle the terrorist infrastructure – until Hamas is decisively defeated."

Meanwhile, the United Nations said no humanitarian aid had been distributed yet in Gaza, although Israel eased its 11-week-old blockade on Monday.

"Israeli authorities are requiring us to offload supplies on the Palestinian side of Kerem Shalom crossing and reload them separately once they secure our team's access from inside Gaza," said UN spokesperson Stephane Dujarric.

Dujarric said four trucks of baby food were dropped off on the Palestinian side of the border on Monday, and that a few dozen trucks of flour, medicine, nutrition supplies and other basic items entered Gaza on Tuesday.

Israel's military said 93 UN aid trucks entered Gaza on Tuesday via Kerem Shalom "after a thorough security inspection."

The hunger crisis in Gaza deepened after Israel imposed a blockade on supplies from March 2. The UN says at least 500 trucks of aid and commercial goods need to enter Gaza every day to alleviate the humanitarian crisis.

Louise Wateridge of the UN Palestinian refugee agency – UN Relief and Works Agency for Palestine Refugees in the Near East – said on Tuesday there was little food left.

"Everything's empty. The warehouses, the distribution centers, they've been empty for weeks," she said. 

Besides, indirect ceasefire talks between Israel and Hamas in Qatar appeared to falter again, with Israeli Prime Minister Benjamin Netanyahu saying he had decided to bring back the senior negotiating team from Doha for consultations.

In a statement issued on Tuesday, Hamas announced it holds the Israeli government "fully responsible" for failing efforts to reach an agreement.

Hamas said the low-level Israeli team left in Doha lacks any authority to reach an agreement, accusing Netanyahu of "misleading world public opinion and pretending to participate in the negotiation process." According to Hamas, no real negotiations have taken place since Saturday.

Israel's ground and air offensive has displaced nearly all Gaza's 2.3 million residents and killed more than 53,000, according to Gaza health authorities.
