Air France and low-cost carrier Transavia France said Wednesday their flights between Paris and Beirut would remain suspended till the weekend due to the “security situation” in Lebanon.

The two airlines had planned to resume flights on Wednesday, but said they will now remain grounded until Saturday.

“The resumption of operations will be subject to a new assessment of the local situation,” an Air France statement said.

Both carriers stopped servicing the route on Monday, a day after Israel vowed to retaliate following rocket fire it blamed on Lebanese armed group Hezbollah that killed 12 people in the Israeli-annexed Golan Heights.

The rocket attack on the Golan sparked fears that fighting between Hezbollah and Israel would escalate.

When those fears subsided somewhat they announced on Tuesday that flights would resume on Wednesday.

But Israel then struck a Hezbollah stronghold in south Beirut on Tuesday evening, targeting a senior commander it blamed for the rocket strike on the Golan Heights.

Hezbollah said Wednesday the commander was inside the building hit by Israel but that his fate remained unknown.

German carrier Lufthansa has suspended flights until August 5.

Air France and Transavia both belong to the Air France-KLM group.
