US gives Israel 30 days to boost Gaza aid or risk cut to military support

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.
