South Korea's ruling conservatives push a controversial free trade deal with the United States through parliament on as legislators scuffle and one opposition MP lets off a teargas device, briefly clearing the chamber.<br/> The deal, which economists believe could boost the $67 billion in annual trade between the two countries by as much as a quarter, had been stalled in the Korean parliament as the government shied away from forcing it through for fear of violent confrontations in the legislature.<br/> The bill was passed with an overwhelming majority as most members of the opposition Democratic Party abstained from the vote.
