A bomb has exploded in Pakistan's port city of Karachi, killing two people.
Police say the motive behind the attack in Karachi's Sohrab Goth neighborhood on January 30 was unknown.
Pakistan's largest city is routinely affected by violence.
Last week, twin bomb explosions killed four people, including police officers.
Some 2,000 people were killed in the city in 2012 in violence linked to ethnic and political tensions.
