Two Pakistani Taliban leaders have recently been killed mysteriously in Afghanistan’s capital Kabul, Tehrik-e-Taliban Pakistan (TTP) confirmed late Thursday night.

Sheikh Khalid Haqqani, the former deputy chief of TTP and member of the group’s central committee, along with another commander Qari Saif Peshawari were killed during a fight with forces in Afghanistan on Jan. 31, Mohammad Khurasani, the outlawed militant group spokesman said in a statement.

Khurasani did not disclose details about the incident but said he was on his way for carrying out an attack when Afghan forces stopped his way and killed him.

Afghan government kept it secret and did not share information with the public in this regard.

The questions are why the TTP leaders were in Kabul, how and who killed them.

Another source from TTP said they believe the murder was done by Pakistan’s intelligence service, ISI.

The source confirmed the dead bodies were found near the luxury InterContinental Hotel, in Kabul.
