BEIRUT, Lebanon, Feb 16, 2025 (BSS/AFP) - Lebanon denied permission for Iranian flights to land in Beirut twice this week after the United States warned Israel might shoot the planes down, a Lebanese security source told AFP Saturday.

The first incident occurred on Thursday, when Lebanese authorities sent word to Iran that a Beirut-bound flight should not take off.

"Through the Americans, Israel informed the Lebanese state that it would target the airport if the Iranian plane landed in Lebanon," the source said.

"The American side told the Lebanese side that Israel was serious about its threat," the source added.

Lebanon's public works and transport ministry then refused clearance for the flight, after consulting the prime minister and president, the source added.

The message was passed on before the flight took off, said the source.

Another flight was also barred from taking off from Iran on Friday, which prompted protests in Lebanon from supporters of the Iran-backed Hezbollah group, who blocked the road to the country's only international airport.

"The security of Beirut airport takes precedence over any other consideration," Lebanese Prime Minister Nawaf Salam said Saturday.

"And the safety of travelers as well as the safety of Lebanese citizens are elements on which we will not compromise."

Israel has on several occasions accused Hezbollah of using the airport in Beirut to bring in weapons from Iran. The group -- and Lebanese leaders -- have denied those allegations.

A fragile ceasefire has been in place in Lebanon since November 27, after more than a year of hostilities and two of months of open war between Israel and Hezbollah there.
