A powerful car bomb exploded in southern Pakistan on Sunday, killing at least 20 people and injuring 90 others, officials said, DPA reported.
Several apartments and businesses were destroyed when the explosives-packed car detonated in the densely populated and Shiite dominated Abbas Town neighborhood of Karachi, police official Azhar Iqbal told dpa.
It remains unclear if the bombing was a suicide attack or whether the car was trigged remotely.
The port city of Karachi, the most populated city in Pakistan, has seen an uptick in violence in recent years, and Sunday's blast comes amid rising sectarian attacks throughout the country ahead of elections set for May.
There was no immediate claim of responsibility for the bombing, but the banned Lashkar-e-Jhangvi group has said they were behind a string of attacks on Shiites and Hazara ethnic minorities in recent months.
