2 killed in explosions near anti-Taliban party headquarters in Karachi, Pakistan

(CNN) -- Two people were killed and 20 more injured in back-to-back explosions near the headquarters of an anti-Taliban political party in Karachi, Pakistan, police told CNN on Saturday.

The explosions took place near the headquarters of Muttahida Quami Movement, or MQM, police spokesman Mureed Abbas said.

The MQM, which is Pakistan's most liberal and secular political party that is firmly opposed to the Islamist militant group, has been targeted by the Pakistani Taliban in recent weeks.

President Asif Ali Zardari strongly condemned the bomb blasts and expressed sympathies for those killed and injured and their families.

A candidate in this month's national elections was shot and killed Thursday by two gunmen on a motorbike, a senior police official in Hyderabad said. Candidate Fakhar Ul Islam was targeted on his way home from his office and was a member of MQM.

Pakistani Taliban leader Hakimullah Mehsud has told Pakistanis to stay away from the elections.

On May 11, Pakistanis will go to the polls to elect a new civilian government for a five-year term.
