Police officials said Saturday that security forces had arrested five terror suspects from the Choti area of the town of Dera Ghazi Khan late Friday.

“During their interrogation, the militants confessed to plotting terror attacks on the Shia Imam Bargahs, Mosque, and other sensitive places,” unnamed officials added.

They said that the arrested militants are members of a group known as “Tehrik-e-Taliban Pakistan” and were trained in the South Waziristan Agency.

The detainees had been moved to a secret location for further questioning, the officials added.

The Taliban-linked Wahhabi groups in Parachinar, Hangu District and much of the Kurram tribal agency have mounted a series of violent attacks against the region’s Shia Muslims.

The most recent incident occurred on Friday when a suicide bomber blew up an explosives-laden car at a market in Usterzai, a Shia majority town on the outskirts of Kohat in northwest Pakistan. At least 30 people were killed and 70 others wounded in the incident.
