Bodies of 13 bus passengers, who had been abducted Monday night and later killed, were found in a mountainous region of Pakistan's Balochistan province Tuesday, the Geo News reported.
The coach, heading from Punjab to Quetta city, was carrying 15 passengers when they were kidnapped near Mach town of the province's Bolan district. Thirteen bodies were recovered from nearby mountains, a senior police official said.
The Baloch Liberation Army has claimed responsibility of the killings, the report added.
A district administration official said approximately 200 militants dressed in security forces uniform carried out the attack.
