The main airport in Bangkok has been locked down by soldiers as the Thai capital prepares for anti-government demonstrations.

From Thursday 11th until the 23rd of March, supporters of the former prime minister Thaksin Shinawatra have warned they will protest throughout the country, and especially in Bangkok.

In 2008, Thaksin supporters invaded the airport, preventing flights from taking off and landing.

The airport now has a plan for the impending demonstrations, which it has not announced, but passengers are being forced to check in three to four hours before departure.
