Iran has signaled to Washington that it will respond to Israel's attack on its Syrian embassy in a way that aims to avoid major escalation, and it will not act hastily, as Tehran presses demands that include a Gaza truce, Iranian sources said.

Iran's message to Washington was conveyed by Iranian Foreign Minister Hossein Amirabdollahian during a visit on Sunday to the Gulf Arab state of Oman, which has often acted as an intermediary between Tehran and Washington, the sources said.

A White House spokesperson declined to comment on any messages from Iran but said the United States has communicated to Iran that it was not involved in the strike on the embassy.
