Thailand's 'Red Shirts' have blamed the country's deputy prime minister for the deaths of protestors during a clash with soldiers on 10 April.

They have said they will not end their rally until Suthep Thaugsuban faces charges.

Nattawut Saikua, a co-leader of the United Front for Democracy Against Dictatorship (UDD), known as the 'Red Shirts', said Deputy Prime Minister Suthep Thaugsuban must turn himself in before they would end their protest.

‘Once Suthep turns himself in to the police, the UDD will disperse and return home,’ Nattawut Saikua told supporters.

Mr Suthep has denied he should be held responsible for the deaths during the clash in which 25 people were killed and more than 800 wounded.

The 'Red Shirts' are supporters of ousted premier Thaksin Shinawatra and want immediate elections to replace Prime Minister Abhisit Vejjajiva's government.
