PESHAWAR: One person was killed and six others injured in a blast triggered by an improvised explosive device (IED) targeting a senior leader of a prominent religio-political party in South Waziristan district on Sunday, leaving him in critical condition, police said.

The attack on Maulana Shehzad Wazir comes amid complaints from his Jamiat Ulema-e-Islam (JUI) party about being targeted by militants operating in Pakistan’s northwestern Khyber Pakhtunkhwa (KP) province.

JUI chief Maulana Fazlur Rehman also voiced concerns over militant threats disrupting the party’s election campaign in the region ahead of the February 8 national polls, citing warnings from law enforcement about dangers to its candidates.

“The IED was planted in a street leading to Maulana Shehzad Wazir’s mosque, who is politically affiliated with the JUI-F,” Bilal Wazir, a police officer in Wana, the headquarters of South Waziristan tribal district, told Arab News over the phone. “Mufti Ijaz Wazir died on the spot while six others, including Maulana Shehzad Wazir, who was apparently the target of the attack, were left in critical condition.”

The officer said a police contingent was dispatched to the area soon after the explosion to gather evidence and shift the wounded to the hospital.

Asked about the intensity of the blast, he said it shook the entire neighborhood of Azam Warsak, a settlement on the outskirts of Wana.

Speaking to Arab News, Mufti Ijaz Shinwari, the JUI senior vice president in the tribal area, condemned the incident, saying the victims of the attack were religious leaders and key figures of his political party on the provincial level.

“This is inhumane,” he added. “This is clearly a terrorist attack and a cowardly act.”

No group has claimed responsibility for the attack, though Tehreek-e-Taliban Pakistan (TTP), a banned militant group, has a history of targeting civilians, security forces and politicians in the region, aiming to perpetuate instability in KP.

In recent months, the TTP has claimed responsibility for several attacks and is suspected by officials in others.

Earlier this week, however, Daesh, a separate militant outfit, shot dead Hameed Sufi, a senior leader of the Jamaat-e-Islami party, in the adjacent Bajaur tribal district.

In June, four people, including Maulana Mirza Jan, the president of JUI’s Wana chapter, were shot by unidentified attackers.

Pakistan claims Afghanistan’s Taliban rulers are providing shelter to TTP fighters across the porous border separating the two countries. However, the Afghan Taliban insists they do not allow anyone to use their soil to launch violent attacks in the neighborhood.
