KARACHI: At least two people were killed and around 25 others, including two children, were injured in two separate blasts near an election office of Muttahida Qaumi Movement (MQM) in Karachi on Saturday night, DawnNews reported.

Initial reports suggest the blasts were carried out through planted devices in Orangi Town’s Qasba Colony.

Sources said the first bomb was exploded outside the MQM election office while the second one followed it outside a nearby Shia Imambargah in the area.

DIG district West Zafar Abbas Bukhar, while speaking to Dawn.com, has confirmed the number of casualties.

Explosions were so loud that they were heard from far away. Nearby buildings and vehicles were also damaged in the blast.

Injured are shifted to Abbasi Shaheed Hospital and Qatar Hospital. A complete power blackout was reported in the area after the explosions.

Bomb disposal squad is yet to reach the site. However, security and law enforcement forces have cordoned off the surrounding area.

This is fourth terrorist attack in five days in the metropolis, which is financial hub of the country. At least 23 people have died in these attacks.

Although no group has so far claimed responsibility of the blasts but the outlawed Tehrik-i-Taliban Pakistan (TTP) vowed to target secular political forces of the country, naming Pakistan People's Party (PPP), Awami National Party (ANP) and MQM.

Meanwhile, the MQM has announced to observe a day of mourning throughout the Sindh province on Sunday. The party has appealed to the masses to keep all businesses and transport shut tomorrow.
