According to police, the bomb, which was planted in a motorcycle, went off outside one of the election offices of Muttahida Qaumi Movement (MQM), the apparent target.
The outlawed Tehreek-e-Taliban Pakistan (TTP) has claimed responsibility of today’s attack on MQM.
The TTP had earlier declared democracy ‘un-Isalmic’ and issued threats of attack on MQM, Pakistan People’s Party (PPP) and Awami National Party (ANP).
According to sources, in the beginning it was suspected to be car-bomb, but later it turned out to be a motorcycle blast, however the experts were yet not sure about it.
Initial reports say at least 1-1.5 kilograms of explosives and ball bearings were used in the improvised explosive device.
The bang of the powerful blast, which broke the windowpanes of buildings in the neighborhood, was heard miles from spot. It also damaged a number of cars parked nearby.
The police and emergency response teams have reached the blast site and started shifting the casualties to Abbasi Shaheed Hospital.
The deceased include three blood brothers, said Abbasi Shaheed Hospital’s administration.
MQM Chief Altaf Hussain has condemned the incident in strongest terms.
Moreover, the MQM Coordination Committee has announced a day of mourning tomorrow (Friday).
In a statement issued here, the MQM has urged all the trade and transport bodies keep the businesses closed and public transport off the roads respectively.
The fresh blast pushes the tally of attacks on MQM to three in the run-up to May 11 general elections.
Earlier in the day, Pakistan Ulema Council issued a Fatwa (decree) declaring the casting of vote a ‘religious obligation’.
The decree from the competent Ulema Council came at a time when Pakistan is heading towards May 11 polls amid a wave of terrorists attacks in its three of four provinces and threats to political parties from militants outfits.
