Pakistani Prime Minister Syed Yousuf Raza Gilani dashed to Karachi today on a two day trip to review the deteriorated law and order situation in the commercial hub of the country, as death toll in riots soared to 90. Official sources said, Mr. Gilani would hold separate meetings with all political parties in an attempt to broker a truce between the conflicting coalition partners. Since the outbreak of violence following the assassination of Muttahida Qaumi Movement (MQM) legislator Raza Haider on Monday in Karachi, some 90 people have been killed and over 200 wounded and more than 100 vehicles have been torched.
