US Secretary of State Marco Rubio is meeting Israeli Prime Minister Benjamin Netanyahu in Jerusalem, with the aftermath of Israel's strike in Qatar expected to be high on the agenda.
Last week's strike, which targeted senior Hamas leaders on the close US ally's territory, drew international outrage and was criticised by President Donald Trump.
Rubio earlier said: "Obviously we're not happy about it. The president was not happy about it. Now we need to move forward and figure out what comes next."
The meeting comes as Arab leaders hold a summit in a show of support for Qatar. Its prime minister urged the international community to stop applying "double standards" and to punish Israel.
The Gulf state hosts a major US airbase and has played a key role in brokering diplomatic efforts to end the war in Gaza, serving as a mediator of indirect negotiations between Hamas and Israel.
