The Counter-Terrorism Department said on Tuesday that it has arrested three terrorists involved in the Rawalpindi bomb blast.
A statement issued by the CTD-Lahore said the militants admitted to carrying out four terrorist attacks in Pakistan and planned to bomb the Islamabad Stock Exchange. It said the militants had financial links to terrorist organisations operating from Afghanistan.
The department said it seized explosives during the operation.
At least 25 people were injured in an explosion near the Ganj Mandi police station in Rawalpindi on Sunday. Initial reports suggested it was a hand grenade attack.
City Police Officer Rawalpindi Mohammad Ahsan Younas said it was the second attack near a police station in 10 days.
In the last attack, on December 4, at least one man was killed and seven others were injured when an improvised explosive device exploded near the Pir Wadhai police station.
