Trump said on Monday that Iran has a "last chance" to make a deal.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Delegations from the U.S. and Iran entered negotiations in June aimed at a war-ending deal based on a memorandum of understanding signed by both countries.
The U.S. and Iran have nonetheless continued to exchange strikes, with the strategic Strait of Hormuz the primary flashpoint.
Talks between Israel and Lebanon ended early on Wednesday due to events on the ground, but will reconvene Thursday morning, according to a State Department official.
Discussions focused on a range of political and military issues and were extremely productive, the official said. The technical teams made progress on determining key details on implementation of the Trilateral Framework.
A joint statement to be released by Iran and Oman regarding the passage of vessels through the Strait of Hormuz is in the final drafting stage, Iranian foreign ministry spokesperson Esmaeil Baqaei said Wednesday.
Oman and Iran have been in talks aimed at establishing a safe passage route for commercial shipping in the strait for two months.
The geographical coordinates of the proposed route have been agreed upon, and if certain third parties do not obstruct this process, the joint statement between the two countries, including key considerations and points of agreement, is in the final stages of review and drafting, Baqaei said.
The Israel Defense Forces said in a statement that it launched strikes against Hezbollah in southern Lebanon on Wednesday in response to an alleged ceasefire violation by the Iran-aligned group.
The Israeli military issued an evacuation warning to residents of the village of Al-Mansouri in southern Lebanon ahead of the strikes.
"Following the IDF's evacuation notice, the Al-Mansouri village is located within the Security Zone, where the military activities are still ongoing and can risk the lives of those in the area," the IDF said in a statement.
Addine, "The IDF issued an advanced warning to the civilians in the area in order to protect their safety. The civilians reached the area under the auspices of the Lebanese Armed Forces, which established a checkpoint in the area in violation of the understandings."

Iran executed at least 56 people on national security-related charges since March 19, including 27 individuals in cases linked to nationwide protests in January, United Nations High Commissioner for Human Rights Volker Turk said in a statement on Wednesday.
More than 100 people are at risk of execution on similar charges, Turk said, adding that executions for drug-related offences are also continuing at "an alarming rate."
"Persistent lack of fair trial and due process guarantees are deeply troubling. Confessions have allegedly been obtained under torture and other ill-treatment," Turk said.
"Several executions have reportedly been carried out in public. Some have reportedly been carried out only weeks after arrest. Twelve defendants were reportedly sentenced to death following a single three-hour closed-door hearing," he added.
