Cancellations come amid fears of conflict between Israel and Hezbollah following rocket attack.

Flights at Beirut airport have been cancelled or delayed with Lebanon’s Middle East Airlines (MEA) saying disruptions to its schedule were related to insurance risks, as tensions escalate between Israel and the armed political group Hezbollah.

Lufthansa on Monday said it had suspended five routes to and from Beirut by the group’s carriers Swiss International Air Lines, Eurowings and Lufthansa up to and including July 30 “in an abundance of caution”.

A rocket attack that killed 12 teenagers and children in the Israeli-occupied Golan Heights on Saturday has added to concerns that Israel and the Iran-backed group could engage in a full-scale war.

Israel’s Security Cabinet on Sunday authorised the government to respond to the attack.

Hezbollah has denied any responsibility for the attack, the deadliest in Israel or Israeli-annexed territory since Hamas’s October 7 assault sparked the war on Gaza, which has since spread to several fronts.

Beirut airport’s flight information board and flight tracking website Flightradar24 shows Turkish Airlines also cancelled two flights overnight on Sunday.

Turkey-based budget carrier SunExpress, Turkish Airlines subsidiary AJet, Greek carrier Aegean Airlines, Ethiopian Air and MEA have also cancelled flights scheduled to land in Beirut on Monday, Flightradar24 shows.

The airlines did not immediately respond to requests for comment.

Beirut-Rafic Hariri International Airport is Lebanon’s only airport.

It has been targeted in the country’s civil war and previous fighting with Israel, including in the last war between Hezbollah and Israel in 2006.

On Sunday, MEA said it had delayed the departure of some flights set to land in Beirut overnight.

Additional delays to flights landing on Monday were then announced due to “technical reasons related to the distribution of insurance risks for aircraft between Lebanon and other destinations”, MEA said.

Hezbollah and the Israeli military have increased cross-border exchanges of fire since the Gaza war began.

The conflict has disrupted flights and shipping across the region, including during reciprocal drone and missile attacks between Israel and Iran in April.

Lufthansa had already suspended night-time flights to and from Beirut for July due to “current developments” in the Middle East.
