A general view of damage at the scene of a bomb explosion targeting an election campaign office of the Mutahida Qaumi Movement in restive Karachi, Pakistan, on Saturday.
Two bomb blasts — the fourth and fifth in two days — shook the largest city in Pakistan late Saturday, according to local media.
Local media reported that at least two people were killed and 20 injured in Karachi in the first blast, a car bomb that was accompanied by a grenade attack.
Sharfuddin Memon, the special security adviser to the Pakistani province of Sindh, which includes Karachi, told NBC News that “there might be several casualties” in the first bombing.
Col. Shafiq Ahmed, a spokesman for the paramilitary unit that polices Karachi, told NBC News that emergency measures were being taken and that there was an unscheduled high-level security meeting under way in Karachi.
The first bombing Saturday was in a residential area and the second in Karachi’s largest slum, Lyari.
There were no immediate claims of responsibility. The Taliban claimed responsibility for the previous three bombings, which targeted rallies and offices of liberal political parties. Pakistan holds national elections May 11.
