The dreaded Islamic State militant group on Thursday claimed responsibility for the attack on a Pakistani media house that had injured one person.
Unidentified assailants riding a motorbike lobbed a hand grenade on ARY News office and fired several shots on Wednesday.
Security guards present at the office entrance retaliated forcing the attackers to flee away dropping pamphlets, ARY news said in a report.
Global terror outfit ISIS's Afghanistan chapter claimed responsibility of the attack in the pamphlets 'in reaction to the channels coverage of ongoing operation Zarb-e-Azb'.
In the attack, a non-linear editor was injured who was hit by a shrapnel in the head. He was immediately whisked to a hospital for medical attention.
Prime Minister Nawaz Sharif denounced the attack in strongest words. He directed the authorities to provide security to ARY News employees.
A probe is going on and no arrest has been made in the case, police said.
Pakistani police said in December they arrested eight suspected IS extremists after a raid in the central province of Punjab, accusing them of planning attacks.
Pakistan has officially denied that Islamic State organisation is operating in Pakistan, but authorities have expressed fears the extremists could find recruits among the country's myriad Islamist militant groups.
