Nepal's airport bans carrying of liquids by passengers

"As part of precautionary measures, security at Tribhuvan International Airport has been put on high alert," said police superintendent Prakash Kunwar.

"Passengers have been barred from carrying aerosols, gels, mouthwash, toothpaste, perfumes, liquid soaps, shaving creams and other forms of liquids in hand luggage," he said.

International airlines fly from Tribhuvan International in Kathmandu to 12 countries, Kanwar said.

The security was stepped up after British police said Thursday they foiled a plot to smuggle liquids in hand baggage onto planes bound for the United States from London's Heathrow Airport that would be made into bombs.

Kanwar said Nepal authorities were "strictly monitoring Delhi-bound flights as India has raised security at its major airports".

India on Friday announced stringent security measures at five key airports in the country after Britain said it had uncovered the plan to blow up flights and US warnings Friday of possible Al-Qaeda attacks in India.
