Iran's Foreign Minister Mohammad Javad Zarif began a two-day visit to Lebanon on Tuesday by meeting Prime Minister Tammam Salam.

“We discussed cooperation between the two countries and bilateral ties,” said Zarif after the Grand Serail talks.

Iran's Foreign Minister Mohammad Javad Zarif is scheduled to visit Beirut next week to brief Lebanese officials on the nuclear deal signed between major powers and Tehran.

Zarif will make the visit on August 12. He is expected to meet with top officials and political figures who are allied with Iran.

President Barack Obama has warned that any possible rejection by the Congress of the Iran nuclear deal, would force the U.S. to attack Iran, a move that could lead to a Hizbulalh retaliation against Israel.

"It would be destructive both to the U.S. and to Israel," Obama told Jewish leaders on Tuesday, according to Israeli media reports.

Iran's Ambassador to Beirut Mohammed Fathali has stressed that it was up to Lebanon's rival leaders to resolve the country's presidential deadlock.

“This is an internal Lebanese issue,” the diplomat told al-Akhbar newspaper in an interview published on Friday.

Israel has deployed the Iron Dome defense system to the north on the border with Lebanon, likely amid fears that Hizbullah could get an infusion of cash and weapons from Iran after the nuclear deal.

In an exclusive interview with FoxNews.com, the commander of Israel’s Active Defense Air Wing, Col. Yoni Saada Marom, said that the military drills were not a direct reaction to recent events, but made clear that Hizbullah and other groups close to Israel's borders presented a potentially heightened threat.

Speaker Nabih Berri has reiterated that the government of Prime Minister Tammam Salam is a red line, urging Lebanon's rival officials not to wait for the Iran nuclear deal to resolve the country's crises.

“Bringing down the cabinet means abolishing the country. This cannot take place,” Berri told his visitors, according to al-Joumhouria daily published on Friday.

French Foreign Minister Laurent Fabius has urged his Iranian counterpart Mohammad Javad Zarif to exert efforts to end Lebanon's presidential crisis, informed sources said.

The Iranian sources told pan-Arab daily al-Hayat published on Thursday that Fabius told Zarif about the importance of contacting Lebanese parties that are allied with Iran to urge them to find a solution to the deadlock.

Top U.S. military officers sought to reassure worried lawmakers Wednesday that U.S. forces would check Iran's "malign" influence in the Middle East should Congress greenlight the nuclear deal with Tehran.

Many Republicans and some skeptical Democrats have voiced concerns that the historic accord reached with the Islamic republic this month in Vienna would trigger a regional nuclear arms race, embolden and strengthen Iran and put key U.S. ally Israel in jeopardy.

Officials close to Prime Minister Tammam Salam were not optimistic on Wednesday on a possible solution to Lebanon's political crisis as top diplomats rushed to his support to stop a possible resignation decision.

The officials, who were not identified, told al-Joumhouria daily that “all efforts, which had been exerted until Tuesday, hit a dead-end as a result of inflexible stances that caused a failure in coming up with solutions” to controversial issues.

A bomb blast killed two Bahrain policemen and wounded six others Tuesday in an area often shaken by clashes between security forces and Shiite Muslim protesters, the interior ministry said.

Bahrain has seen frequent unrest since the minority Sunni rulers of the small Gulf kingdom crushed a Shiite-led uprising four years ago.
