Iran on Sunday reportedly fired missiles at Israel, as a tenuous ceasefire between Washington and Tehran hangs in the balance.

The reports of missile fire from Iran come after the Iranian Parliamentary Speaker, MB Ghalibaf, said in a post to X that the U.S. "naval blockade and violation of agreements regarding Lebanon" amount to violations of the ceasefire.

The White House confirmed to MS NOW that President Donald Trump has been briefed on renewed fighting after Iran fired a missile at Israel for the first time since the ceasefire began. The briefing was first reported by Axios.

Ghalibaf said that the military activity in Lebanon and the ongoing U.S. blockade made "American and regime bases and assets in the region into legitimate targets," according to a translation on X.

CNBC cannot confirm that the missiles were fired. The Associated Press reported Sunday that Israel said Iran had launched missiles at it, and the Israeli Defence Forces said they were operating defensive systems after identifying the missiles.

Trump on Sunday told Fox News that the missile attacks are "certainly not going to help negotiations."

Axios later reported that Trump was going to call Israeli Prime Minister Benjamin Netanyahu to urge him not to strike back at Iran.

In a statement to The New York Times, Iran's Islamic Revolutionary Guard Corps said the ceasefire "was conditional on a cease-fire on all fronts."

"Tonight's operation was a warning, and if aggressions are repeated, the responses will be broader," the statement read.

The fragile ceasefire between the U.S. and Iran has been in place since early April. But fighting between Israel and Iran-backed Hezbollah in Lebanon has complicated the temporary peace as negotiators struggle to broker a deal to end the conflict.

Iran has demanded an end to hostilities in Lebanon and a halt to the U.S. blockade of its ports and ships. The U.S., in turn, is demanding that Iran hand over its nuclear material and agree to never obtain a nuclear weapon.

The Trump administration is reportedly considering redirecting Iranian assets to allied Gulf states to pay for rebuilding damage done by Iranian strikes.

Iran's Deputy Foreign Minister Kazem Gharibabadi appeared to respond to those reports by saying that regional governments were "not in a position to demand reparations," Reuters reported Sunday. Gharibabadi said in a post on X that Iran's assets were "neither war spoils for Washington nor a payment fund for its allies."
