According to the Dan newspaper of Pakistan, armed men attacked the police headquarters in the city of Karachi, Pakistan, and the conflict continued for hours.
It is said that several explosions were also heard.
Mortaza Wahab, the spokesperson of the Sindh state government, said that 4 people were killed and 17 others were injured in this conflict.
Tehreek-e-Taliban Pakistan (TTP) has claimed responsibility for this attack.
This is despite the fact that last month as a result of the attack of armed men on the police complex in Peshawar city, around 100 people were killed and thousands of others were injured.
