The US government has denounced the shelling of a United Nations school in Gaza that killed 15 people as “totally unacceptable and totally indefensible”.
Israel is being widely blamed for the strike on the school in the Jabaliya refugee camp, which occurred despite warnings that the school was being used as a civilian shelter.
In the strongest criticism of the Gaza offensive yet from the US, Israel’s closest ally, White House spokesman Josh Earnest said Israel’s government and military are not doing enough to spare civilian lives.
“The shelling of a UN facility that is housing innocent civilians who are fleeing violence is totally unacceptable,” he said.
The US had earlier refused to apportion blame for the attack.
More than 3,000 people, including many women and children, had been sheltering at the Abu Hussein School when it was attacked.
Israel says it is investigating the strike.

UN leaders are left lost for words after a Gaza shelter housing thousands of civilians is shelled.
Gaza health officials say more than 1,400 Palestinians, most of them civilians, have been killed in the battered enclave since conflict flared more than three weeks ago.
Israel says 56 of its soldiers and three civilians have been killed by rockets fired by the Hamas militant group.
Mr Earnest urged Israel to end its ground operation in Gaza, saying: “These reports that hundreds of innocent Palestinian civilians have been killed are tragic.”
He repeated US calls for an immediate ceasefire and urged Hamas to stop firing rockets at innocent Israeli civilians.
Seven UN staff have died in the violence, and the UN Security Council overnight held a tense meeting on the conflict.
UN officials describing the situation in Gaza as extreme and suggested Israel was deliberately defying international law.
Palestinian ambassador Riyad Mansour said anyone would be moved by their reports.
“[Anyone] would be crying from pain and shame for the fact that this – in the 21st century – this genocide is being unleashed,” he said.
Israel’s ambassador Ron Prosser said Israel has no choice.
“It’s time to abandon romantic notion as Hamas as freedom fighters. This is a radical terror organisation with a global Islamist agenda,” he said.
The UN’s human rights official Navi Pillay said world powers should hold Israel accountable for possible war crimes.
Ms Pillay said Israel’s actions seemed to be in “deliberate defiance of obligations that international law imposes”.
Netanyahu vows to destroy tunnels ‘with or without ceasefire’
Both Israel and Hamas have voiced openness to a truce, but their terms diverge dramatically.
Israel wants Gaza stripped of infiltration tunnels and rocket stocks. Hamas rules that out, and seeks an end to a crippling Gaza blockade enforced by Israel and Egypt, which view the Palestinian Islamists as a security threat.
Israel briefly observed a July 15 ceasefire proposed by Egypt, but Hamas continued attacks, saying its conditions had been ignored.
Egyptian officials say they put together a revised truce plan this week that had been provisionally accepted by Israel, though Hamas was still undecided.
Israeli prime minister Benjamin Netanyahu has said he would not accept any ceasefire that stopped Israel completing the destruction of militants’ infiltration tunnels.
The Israeli military estimates that accomplishing that task, already into its fourth week, will take several more days.
“We are determined to complete this mission, with or without a ceasefire,” Mr Netanyahu said in public remarks at a meeting of his full cabinet in Tel Aviv.
“I wont agree to any proposal that will not enable the Israeli military to finish this important task, for the sake of Israel’s security.”
Leaving open the option of widening a ground campaign in the Hamas Islamist-dominated Gaza Strip, the Israeli military said it had called up an additional 16,000 reservists.
A military source said they would relieve a similar number of reserve soldiers being stood down.
Fighting, however, appeared less ferocious than on previous days this week – more than 100 were killed on Wednesday alone.
Gaza health officials said 19 Palestinians were killed in Israeli assaults on Thursday, which included an air strike on a van in the heart of Gaza City, which killed two people.
The Israeli military said more than 60 rockets were fired from the Palestinian enclave, some deep into Israel.
One person was moderately wounded by a Gaza projectile that struck in the southern town of Kiryat Gat.
Hamas said it fired one rocket at Tel Aviv, which the military said was intercepted.
