US Senator Chris Murphy told CNN on Sunday that the number of casualties in Gaza is unacceptable, while US National Security Adviser Jake Sullivan told NBC that the issue of sending conditional aid to Israel is a worthwhile idea.

Murphy said U.S. lawmakers should consider linking aid to Israel to its compliance with international humanitarian law.

U.S. officials are increasingly critical of President Joe Biden's government's handling of the Israeli war on the Gaza Strip.

U.S. officials told the Washington Post today that 20 White House staff had asked to meet Biden's top advisers for a discussion on the Gaza Strip.

The US president has declared unconditional support for Israel in its war on Gaza, but the high number of casualties in the Strip has prompted him to take a tougher approach with Tel Aviv.

In early November, a US official confirmed during a congressional hearing that anger was mounting in the Middle East against the United States and Israel over the war on Gaza, while another official spoke of constant US warnings to Tel Aviv that civilian casualties should be minimized.
