ISIS has reportedly claimed responsibility for a suicide bombing on Sunday that killed at least 54 people and injured over 200 others, Fox News reports.
The bombing occurred at a political rally in Bajur, a district in northern Pakistan on the border of Afghanistan, according to CBS News.
The rally was organized by the Jamiat Ulema Islam party, which is headed by Fazlur Rehman, who was not at the event. Rehman has been a vocal supporter of Afghanistan’s Taliban government.
"People were chanting God is Great on the arrival of senior leaders, when I heard the deafening sound of the bomb," said local resident Khan Mohammad, who had been standing outside of the tent where over 1,000 people had gathered on Sunday as their party prepared for parliamentary elections.
According to the Associated Press, provincial police said that the attack was carried out by a suicide bomber wearing an explosive vest. The vest was set off in close proximity to the stage where several senior party leaders were sitting.
"There was dust and smoke around, and I was under some injured people from where I could hardly stand up, only to see chaos and some scattered limbs," said Adam Khan, who was knocked to the ground by the blast and injured.
