Palestinian Authority President Mahmoud Abbas said the US veto of a UN Security Council resolution demanding a humanitarian ceasefire in Gaza made it complicit in what he described as war crimes against Palestinians.
Abbas also said he held the US responsible for the bloodshed of Palestinian children, women and the elderly in the Gaza Strip, a statement released by the presidency said.
The United States wielded its UN Security Council veto on Friday to shield Israel from a global demand for a ceasefire.
Thirteen of the Security Council's 15 members voted for the resolution calling for an immediate humanitarian ceasefire that was blocked by Washington. Britain abstained.
