Thai anti-riot police fired tear gas and detained dozens of demonstrators as clashes erupted at the first major street protests against Prime Minister Yingluck Shinawatra’s government.

At least seven police were wounded and up to 132 protesters arrested. Pitak Siam, a new anti-government group, has attracted the support of various royalist groups including “yellow shirt” members of the People’s Alliance for Democracy.
