Hundreds of Israeli travellers have been stranded at Prague airport for up to three days after an operator of Arkia Israeli Airlines cancelled services due to security concerns in Israel, passengers and the airline said on August 2.

About 400 Israelis have been waiting at the airport, with some sleeping on the floor, as Arkia struggles to find alternative arrangements to bring them home.

"Everyone here is sprawled out like dogs on the floor for three days now. There are families with children and elderly people," one stranded passenger told Israel's Kan channel.

Arkia said it was "doing everything to solve the problem" and expected two flights to depart, one at midday using a particular aircraft brought from Poland and another in the evening.

The incident highlights broader disruptions to air travel as foreign airlines cancel or reduce flights to Israel amid heightened regional tensions following assassinations reportedly carried out by Israel in Beirut and Tehran.

Israel's Airports Authority warned travellers to expect possible delays in returning to the country.

The website of Ben Gurion Airport in Tel Aviv announced on August 2: “Dear passengers, please be advised that Ben Gurion airport is working as planned, including departures and landings.”

Several flights on the flight board appear as cancelled, including Arkia Israeli Airlines flights to Corfu and El Al flights to New York, while later flights out of the country appear to be on time.

Industry sources estimate tens of thousands of Israelis may be stuck abroad without return flights due to the security situation.

Israel's transportation ministry said that the security situation still allows flights to and from Israel, but some foreign airlines are suspending or reducing services for their own internal reasons.
