>> A startling claim from Islamic State in the wake of Monday's massive suicide bombing in Pakistan. The Muslim extremist group putting out a message claiming responsibility for the blast which killed at least 70 people and wounded more that 100 at a hospital in the eastern city of Quetta.
The ISIS media arm saying quote, a martyr from the Islamic State detonated his explosive belt. If that were true, it would be an alarming development for Pakistan, which has long been plagued by militant violence but most of it's been locally based and rarely involves Middle Eastern groups like ISIS.
As Mehreen Zahra-Malik explains from Islamabad, many are skeptical of the claim.>> Most people in Pakistan are not taking the ISIS claim seriously. They're calling it dubious. A majority of experts suggest that there is no organizational footprint of ISIS in Baluchistan. Of course, there are some groups who say that they have joined ISIS, or who swear allegiance to ISIS, but they have done this to get importance, to catch attention, or because they're inspired by the successes of ISIS in Syria and Iraq.
On the other hand, of course, there is a large presence of sectarian militant groups in Baluchistan with an anti-Shia agenda. ISIS is a mindset, and people of that mindset are present in Baluchistan. If this claim that ISIS is now behind this attack is true, then it's very alarming because it would mean that Baluchistan could become the new front in the fight against terrorism.
>> The motive behind the mass killing is unclear, though a number of the dead and wounded were lawyers, many of whom have been targeted in recent attacks in Quetta. Pakistani President Nawaz Sharif has been visiting injured victims.>>
> Their message to him, don't lose courage, we will fight against those who did this with all our might.
