On Saturday, Turkish President Recep Tayyip Erdogan spoke by phone with his U.S. counterpart Donald Trump, expressing Ankara’s readiness to “do everything possible to prevent an uncontrolled escalation of tensions” between Israel and Iran, Anadolu Agency reports.

According to Turkey’s Communications Directorate, the two leaders discussed the Israel-Iran conflict as well as regional and global issues. Erdogan said Turkey is closely monitoring the rising tensions between Iran and Israel and emphasized that negotiations on Iran’s nuclear program are the “only way” to resolve the dispute.

He “expressed support for the U.S. position that nuclear talks must continue to address the issue.” Trump also called on Iran to reach a deal on its nuclear program before it’s too late.

However, the sixth round of indirect talks between Tehran and Washington, scheduled for Sunday in Muscat, was canceled.

On Friday, Israel attacked Iran’s nuclear and military facilities, killing senior commanders and leading scientists. The attacks have continued since, with Iran launching retaliatory strikes.
