In Karachi, a city in southern Pakistan, armed men attacked a police compound, killing at least two persons in the process.
On Friday, gunfire and explosions were reported outside the location, which has many police buildings and officer housing.
According to government officials and Ghulam Nabi Memon, police chief for Sindh province, of which Karachi is the city, at least one police officer and a civilian were murdered, and 11 members of the security forces were wounded.
After several hours, security personnel retook the building and killed three attackers, according to a government spokesman. A security search was in progress as bomb disposal specialists and police commandos entered the structure.
The Pakistani Taliban, also known as Tehreek-e-Taliban Pakistan (TTP), took credit for the assault.
The attack in the largest business hub of Pakistan was denounced by President Arif Alvi.
After a series of lesser explosions, the attack started with a large explosion within the station.
Five to six gunmen, according to Interior Minister Rana Sanaullah Khan, tried to break into the police headquarters while hurling hand grenades.
Armed group attacks have increased in Pakistan after the Pakistani Taliban unilaterally violated a months-long ceasefire with the government in November.
After a police officer-suicide bomber in Peshawar, Pakistan’s northwest metropolis, killed 101 people at a mosque, the police headquarters in Karachi came under attack. The TTP was accused by the authorities of planning the bombing.
