PARIS - A number of airlines cancelled flights to Mumbai Thursday after attacks across the city left more than 100 people killed and hundreds more injured, operators said.

Italy's flag-carrier Alitalia, which is in severe financial straits, cancelled all its flights to Bombay until further notice, a spokeswoman said. German airline Lufthansa said it had scrapped two flights to Mumbai due to leave Frankfurt and Munich on Thursday.

The two planes had also been due to return from Mumbai with 600 passengers on board, a company spokesman said. The airline was trying to ensure that they can fly home via other Indian cities such as New Delhi.

Air France cancelled a flight from Mumbai to Paris, scheduled to leave at 2:15 am local time (2045 GMT Wednesday), and one from the French capital to the Indian city timed for 10:30 am (0930 GMT), the company said.

Friday's schedule would be maintained as usual, an official added.

US Delta airlines also cancelled one flight from Mumbai to Seattle via Amsterdam, which was to have taken off at 1:50 pm (0820 GMT).

Both Air France and Delta said flight crews overnighting in Mumbai were not hurt in the attacks.

South African Airways delayed the departure of its daily flight to Mumbai by two hours, while British Airways said its services in both directions were normal.
