Police in Pakistan’s restive Khyber Pakhtunkhwa province said on Monday that an initial probe has suggested that the banned terrorist group ISIS is behind the suicide attack on a political convention of a hardline Islamist party that killed at least 46 people and injured over 100.  The attack took place on Sunday when more than 400 members of the conservative Jamiat Ulema Islam-Fazl (JUI-F) party, known for its links to hardline political Islam, had gathered for a meeting under a canopy in the town of Khar, which borders Afghanistan.
