Islamabad: Afghan Taliban's new chief Mullah Akhtar Mansoor was seriously injured in a shootout among the senior commanders of the militant outfit in the border areas of Pakistan following a heated argument, officials said on Thursday.

A militant commander said five people were killed in the firefight and several were injured "including Mullah Mansoor." A local security official confirmed the Tuesday night incident and said Mansoor was shifted to an undisclosed location in Pakistan's volatile Balochistan province by the militants for treatment.
