Pakistani political party office hit by deadly bombings
Three people have been killed by two blasts near the offices of a political party in the Pakistani city of Karachi.
Police said a number of other people were injured in the explosions, which appeared to target the Muttahida Qaumi Movement (MQM), a secular party.
The party, due to take part in national elections next week, has in the past been targeted by Taliban militants.
In the run up to the election, a wave of violence against candidates and rallies has left some 60 people dead.
Such attack are usually blamed on Taliban militants.
Senior police official Saleem Akhtar Siddiqui told the AFP news agency that no MQM members were among those killed in Saturday attack.
The blasts come a day after a prominent member of the party, Mohammad Adil, was shot dead outside a mosque in Karachi.
Also on Friday, gunmen on a motorcycle killed Sadiq Zaman Khattak, a candidate for the Awami National Party (ANP), along with his young son in the city of Karachi, police said.
The attack occurred as Mr Khattak and his son were leaving a mosque after Friday prayers. Four people were wounded.
The elections on 11 May will be the first democratic transfer of parliamentary power in the country, which has a history of military coups.
