Some 570 South Koreans were staying long-term in Israel while around 480 were staying short-term, South Korea's foreign ministry said on Tuesday.

The Ben Gurion Airport was "crowded" and "hectic," said Jang Jeong-yoon, a 62-year-old who was on board the Korean Air flight home after travelling to Israel to take part in the festival of Sukkot.

"As flights were cancelled or delayed, there was fear and people were rushing to leave the country," she said.

Some relatives of those on board the plane were seen waiting at Incheon Airport early Wednesday morning.

No South Korean casualties had been reported, foreign minister Park Jin said on Tuesday. Many of the short-term South Koreans travellers were visiting the country for a pilgrimage.

A Turkish Airline flight on Thursday will also bring 30 South Koreans home, according to the foreign ministry.

Korean Air has cancelled flights departing from Incheon to Tel Aviv on Monday and Wednesday and expects future flights to be irregular.
