Thousands of supporters of Thailand's fugitive former premier Thaksin Shinawatra gathered at temples across the country on Sunday to celebrate his 60th birthday, police said.
Around 60 temples were expected to hold Buddhist ceremonies in his honour, with the largest taking place at Kaew Fah temple in central Nonthaburi province.
"More than 10,000 people have gathered at the temple since the early morning," Police Colonel Songsak Soisuwan told AFP.
"We have around 100 police officers taking care of security. So far the situation is peaceful," he said.
Thaksin, who is living abroad to escape a jail term for corruption, was expected to make a phone-in address to his followers later in the day.
He also marked the occasion by launching accounts on the social networking websites Twitter and Facebook, according to Thaksin's close aide and former lawyer Noppadon Pattama.
"It's another channel for Thaksin to communicate with his supporters. They can sign up to wish him happy birthday or monitor his movements," Noppadon said.
Since Thaksin was ousted in a coup in September 2006, Thai society has been wracked by divisions between his "Red Shirt" supporters among the largely rural poor, and the powerful Bangkok cliques in the palace, military and bureaucracy.
The opponents of Thaksin, known as "Yellow Shirts", staged protests last year that led to a nine-day blockade of Bangkok's airports and left more than 300,000 visitors stranded, badly denting the kingdom's tourist-friendly image.
The "Red Shirts" stormed a key Asian summit in the Thai coastal resort of Pattaya on April 11, forcing its cancellation, before rampaging through the capital, leaving two people dead and 123 injured.
Prime Minister Abhisit Vejjajiva declared emergency rule and protesters clashed with security forces in Bangkok over two days, but finally dispersed after troops surrounded them and threatened to move them by force.
Thaksin fled abroad in August 2008, shortly before being sentenced to two years in prison for conflict of interest concerning a cut-price land purchase by his then-wife Pojaman.
Earlier this month Thailand's highest court began a hearing to determine if authorities can seize about 2.2 billion dollars of his assets, which were frozen by an anti-corruption body soon after he was forced from power.
