The Counterterrorism Department (CTD) in Pakistan’s southern Sindh province said on Saturday it had arrested a key member of the Iran-backed Zainebiyoun Brigade outfit in Karachi, accusing him of being involved in sectarian attacks in the city. Pakistani authorities have arrested several militants affiliated with the Zainebiyoun Brigade in recent years, notably in the country’s commercial hub of Karachi. The city has been a significant recruitment hub for the militant outfit, along with three other regions – Parachinar, Quetta and Gilgit Baltistan. Pakistan’s interior ministry designated Zainebiyoun Brigade as a “terrorist” organization in March 2024, saying it had reasons to believe the outfit was engaged in certain activities “prejudicial to the peace and security of the country.” The CTD said in its press release that Syed Muhammad Musa Rizvi, alias Kamran, was arrested from the city’s Soldier Bazaar area, adding that the accused had been in hiding for fear of being arrested. “The suspect is an important member of the Zainebiyoun Brigade and has been directly and indirectly involved in various sectarian activities that have been regularly funded by the organization,” the CTD said. It said Rizvi had confessed to carrying out a sectarian attack in Karachi’s Taimuria area on Sept. 5, 2023, which had resulted in the killing of a person named Qari Khurram and injuries to two others.
