Pakistani Prime Minister Yousuf Raza Gilani on Friday described those involved in violence in Karachi as 'enemies of our people', after ongoing unrest in the city left at least 85 people dead. Speaking in a televised address to the nation from Karachi Gilani said: 'I would like to make it very clear that those involved in target killings and terrorism pose a threat to Pakistan...they are enemies of our people.' The violence, which has been blamed on political and ethnic rivalry between parties in the province's ruling coalition, continued in Karachi bringing the death toll to 85, a senior police official said on condition of anonymity. Rioters also torched five houses and shops in different neighbourhoods of the southern city late Thursday, said another police officer, Majeed Abbasi. 'Never before in our history, have forces inimical to Pakistan been so active to harm our country... but the government is determined to root out terrorism,' said Gilani, who arrived in Karachi Friday evening. The Prime Minister was due to hold talks with the province's coalition parties in a bid to ease the violence. 'Gilani will hold talks with the coalition partners on the law and order situation in the city,' said provincial government spokesman Jamil Soomro. The prime minister will leave for flood-hit areas of Sindh province on Saturday, Soomro said. The unrest was sparked Monday by the murder of an MP from the Muttahida Qaumi Movement (MQM) party, and continued while catastrophic flooding elsewhere in Pakistan plunged the country into crisis. The violence crippled life in the port city as the MQM, a partner in the Sindh provincial coalition led by the Pakistan Peoples Party (PPP), called for three days of mourning over the murder. The MQM, which represents the Urdu-speaking community, and the Awami National Party (ANP), another coalition partner which speaks for ethnic Pashtun settlers, blamed each other for the violence. Karachi has been largely spared by the Taliban and Al-Qaeda-linked bomb attacks that have dogged northwest Pakistan, but is plagued by ethnic and sectarian killings, crime and kidnappings. This week's unrest marked the deadliest bout of such killings since the province's ruling coalition took office in March 2008. The government has not released exact figures, but rights bodies said 260 targeted killing cases were reported in Karachi during the first six months of this year, compared with 156 during the same period in 2009.
