Condoling with the government in Islamabad and the survivors of the attack, Kana’ani said Iran and Pakistan will not allow enemies to “cause damage to the countries' brotherly relations”.
He added Iran's relevant authorities are continuing their investigation into the tragedy.
Pakistan's Foreign Minister Jalil Abbas Jilani has also lamented the attack, considering it to be a plan on the part of the countries' "common enemies" to disrupt their mutual ties.
The top diplomat urged the Iranian government to take due action against the elements behind the attack.
Unknown assailants gunned down at least nine Pakistani nationals and injured three others in the suburb of the city of Saravan in the province of Sistan and Baluchestan.
The atrocity was perpetrated by three gunmen, who attacked the residence housing the victims, and fled the scene after causing the casualties.
