Violence in Thailand was condemned by MEPs on 20 May 2010.
In a change to the planned agenda, MEPs held a debate on the current conflict between the so-called "red shirts" and government supporters known as "yellow shirts".
Dutch liberal MEP Marietje Schaake said that a state of emergency should not be used to restrict personal freedoms.
A number of people have been killed in violence between protestors and the police in Bangkok, and a curfew has been established.
Irish socialist MEP Joe Higgins said the Thai government were describing the protestors as "terrorists", when in fact they were "impoverished farmers and the urban working class".
