ReutersThe US says the 1.7 million Palestinians crowded into the al-Mawasi area are at “high risk of lethal contagion”The US has written to Israel, giving it 30 days to boost humanitarian aid access in Gaza or risk having some US military assistance cut off.
The letter, sent on Sunday, amounts to the strongest known written warning from the US to its ally and comes amid a new Israeli offensive in northern Gaza that has reportedly caused a large number of civilian casualties.
It says the US has deep concerns about the deteriorating humanitarian situation, adding that Israel denied or impeded nearly 90% of humanitarian movements between the north and south last month.
Israel is reviewing the letter, an Israeli official was reported as saying, adding the country "takes this matter seriously" and intends to "address the concerns raised" with US counterparts.
Israel has previously said it is targeting Hamas operatives in the north and not stopping the entry of humanitarian aid.
On Monday, the Israeli military body responsible for managing crossings into Gaza, Cogat, said 30 lorries carrying aid from the World Food Programme had entered northern Gaza through the Erez crossing.
That ended a two-week period during which the UN said no food aid was delivered to the north, and supplies essential for survival were running out for the 400,000 Palestinians there.
The US is by far the biggest supplier of arms to Israel, and the Israeli military has relied heavily on US-supplied aircraft, guided bombs, missiles and shells to fight the war against Hamas in Gaza over the past year.
