Third day of clashes in Bangkok

Thai troops clashed with protesters for a third day in Bangkok today, as streets in the centre of the city became battlegrounds and authorities struggled to contain Red Shirt demonstrators demanding the prime minister's resignation.

Explosions and street fighting have killed 16 people and wounded nearly 160 since the government attempted on Thursday to seal off the one-square-mile zone the Red Shirts have occupied in one of the capital's most upmarket areas.
