One killed in TV channel office attack in Pakistan

"MQM workers ransacked the premises and fired at the ARY offices", said SSP Saqib Ismail Memon said, adding that their leader" had incited them." teargas shelling to disperse the mob has been carried out by us", he included.

According to a report in The Dawn, the London-based MQM chief also shouted slogans against Pakistan while addressing his party supporters from London over phone on Monday. A cameraman from a different channel, Samaa, was attacked while trying to take video of the events.

Mr Jalil said that one member of MQM staff was shot dead in clashes with security forces and a supporter was shot in the neck and wounded, although this could not be independently confirmed.

Pakistan People's Party (PPP) Chairman Bilawal Bhutto Zardari on Monday strongly condemned the attacks on media houses at Karachi.

Pakistan Paramilitary officers stand guard after sealing the offices of the Muttahida Qaumi Movement, or MQM, in Karachi, Pakistan.

PSP leader said that party workers should not be mistreated due to MQM chief's inflammatory speech. The current camp looked the same until Hussain's address started. "Altaf Hussain enticed his workers to attack journalists and raise anti-Pakistan slogans". The strikers, a lot of them women, attacked a nearby TV channel.

He said MQM leader Farooq Sattar addressed a press conference Tuesday to show his party's democratic position. He said the party should operate from Pakistan until Hussain's health issues are resolved.

It also comes as members of the Karachi Metropolitan Corporation are set to elect an imprisoned MQM politician, Waseem Akhtar, as mayor of Pakistan's biggest and richest city on Wednesday. Since fleeing to London in 1991, Hussain has addressed supporters by a telephone hooked up to a loudspeaker at the party headquarters. The British government gave him a passport in 2002.

"This level of irresponsibility is completely unacceptable and MQM should not only disown such behaviour by its leader but should also provide credible guarantees that such action will not be repeated in future".

Whether the MQM splinters after this incident remains to be seen, but Pakistan's political landscape is scarred by rifts.
