(QHA) -

After weeks of large anti-government demonstrations in the capital, Thai Prime Minister Yingluck Shinawatra dissolved the nation's parliament Monday and called for new elections, informs CNN.

"I don't want our country and the Thai people to suffer from more losses," Yingluck said in a televised address. "I have decided to dissolve the house."

Her announcement came as protesters began marching toward her office, known as Government House, in the latest effort to put pressure on her administration.

A day earlier, Thailand's main opposition party said its roughly 150 members would resign en masse from parliament because they could no longer work with the government.

"This government is no longer justified to run the country, as this house is no longer justified. Today we resign to express that stance," opposition party leader Abhisit Vejjajiva said.

Dissolving parliament and calling elections appear unlikely to placate protest leader Suthep Thaugsuban, a former deputy prime minister for the Democrat Party. He has called for power to be transferred to an unelected "people's council."

As reported earlier, during the weeks of demonstrations, protesters have occupied various government offices. The rallies have been mostly peaceful, but clashes between protesters and government supporters on November 30 left five people dead.
