South Korea ? South Korean lawmakers came to blows in parliament Friday, and at least one was carried from the building on a stretcher, as two political parties fought over control of the speaker’s podium.

Members of the main opposition Grand National Party clashed with pro-government United New Democratic Party lawmakers over bills to impeach three prosecutors who investigated a leading GNP presidential candidate, South Korea’s Yonhap news agency said.

GNP lawmakers tried to block access to the speaker’s podium in the National Assembly using sofas, metal bars and chains, while their UNDP rivals used their hands and power saws to hack through the barriers, Yonhap said. About 100 lawmakers were involved, the report said.

Several lawmakers scuffled at the podium and one, who appeared to have been knocked unconscious, was carried from the hall on a stretcher.
