A crowd of angry protesters have hurled shoes and bottles at Thai Prime Minister Somchai Wongsawat in the latest protest against his government.

Security guards surrounded Mr. Somchai as telecommunications workers attacked him during a visit to their headquarters in Bangkok Wednesday. Some protesters called him a murderer.

Mr. Somchai was not hurt and later told reporters the protest did not bother him.

The prime minister's critics say he should resign to take responsibility for street fighting between police and protesters that left two people dead earlier this month.

Mr. Somchai has been in office for a little more than a month. He says he will not step down, and will await the results of an investigation into the violent protests before deciding what to do next.

The opposition People's Alliance for Democracy has been protesting for months, demanding Mr. Somchai and his predecessors step down because of their links to deposed Prime Minister Thaksin Shinawatra.

The Thai military pushed Mr. Thaksin from power in 2006 for alleged corruption and misuse of power.
