Special Series Middle East conflict Conflict in the Middle East has been escalating. These stories provide context for current developments and the history that led up to them.
"Iran must immediately stop their highly paid PROXIES in Lebanon from causing trouble. If they don't, we'll hit Iran very hard again, just like we did last week, only harder!!!" Trump wrote in a social media post on Sunday.
Iran's lead negotiator, Mohammad Bagher Qalibaf, said on X that Iran's armed forces are prepared to respond to threats.
Middle East JD Vance arrives in Switzerland for talks with Iran over fragile peace deal A day earlier, Iran's military announced it had closed the Strait of Hormuz because of continued Israeli strikes in Lebanon against the Iranian-backed militant group Hezbollah. Iran said the U.S. failure to rein in Israel violated the terms of last week's tentative agreement, which specifies that all fighting in Lebanon must end.
and Iran last week, which is already coming under intense strain. While Iran on Saturday said it had closed the Strait of Hormuz, U.S. Central Command has said shipping through the strait was proceeding normally.
Also under discussion is Iran's nuclear program, another controversial topic. On Sunday morning, Iranian President Masoud Pezeshkian said: "What is certain is that we will never back down from the right to enrich uranium, and the other side is also forced to accept it." Iran has insisted its nuclear program is peaceful.
There's still some additional wood to chop, but we're going to keep on working," Vance said.
The vice president also said the U.S. Other topics covered were "deconfliction mechanisms" for the strait and Lebanon, the diplomat said.
At least 16 people, including civilians, were killed by Israeli strikes on Saturday, according to the Lebanese National News Agency. Israel said the strikes were a response to Hezbollah firing projectiles at its forces overnight on Saturday. Hezbollah said it fired in response to Israel moving toward Lebanese territory.
On Sunday, however, the interim head of the United Nations Interim Force in Lebanon told NPR that for the first time since the war between Israel and Hezbollah started on March 2, the peacekeeping force has recorded no attacks from either side.
Neither Israel or Lebanon have signed the memorandum of understanding, but the agreement calls for respect of Lebanese sovereignty, a provision Iran says the U.S. must enforce. It also calls for a halt to military operations in Lebanon.
"We do everything in our power to protect our people. We don't have a war with Lebanon. We have a war with Hezbollah, who terrorizes Lebanon and seeks our destruction," Netanyahu said at a policy summit in Jerusalem on Sunday. "And when that proxy of Iran is no longer a threat, when it's dismantled, when it's disarmed, yes, we'll have peace with Lebanon.
