The top U.S. and Israeli generals held talks at the Pentagon on Friday amid soaring tensions with Iran, two U.S. officials said on Sunday, speaking on condition of anonymity.

The officials did not offer details about the closed-door discussions between U.S. General Dan Caine, the chairman of the Joint Chiefs of Staff, and Eyal Zamir, chief of staff of the Israeli armed forces. The meeting has not been previously reported.

The United States has ramped up its naval presence ​and hiked its air defences in the ‌Middle East after President Donald Trump repeatedly threatened Iran, trying to pressure it to the negotiating table. Iran's leadership warned on Sunday of a regional conflict if the ⁠U.S. were to attack it.

Israeli ​Defence Minister Israel Katz ​on Sunday met with Zamir after his talks in Washington, Katz's office ‍said, to ⁠review the situation in the region and the Israeli military's "operational readiness for any possible ⁠scenario."
