In August 2015, Punjab home minister Shuja Khanzada announced that five members of the Tehreek-e-Taliban were arrested in connection to the attack.

According to the statement, the men received monetary and material support from India and planned the attack in Afghanistan, from where they came to Lahore.

[13][14] One of the Islamist militant groups allied to the Pakistani Taliban is Jamaat-ul-Ahrar, a breakaway organisation that reunited in March 2015.

The bombings took place during weekly Christian service at the two churches of Yuhanabad neighbourhood located at a distance of half a kilometre apart.

Both churches are located in the Youhanabad area, which is one of the country's biggest Christian localities and is home to at least one million people.

According to Khanzada, they belonged to the TTP's Shehryar Mehsud group and planned the attacks inside Afghanistan, from where they came to Lahore.

[26] Politicians, religious leaders and members of the civil society condemned the attacks, while calling for stricter security measures.

However, the lynching by the mob was also condemned and Interior Minister Chaudhry Nisar Ali Khan termed it as "the worst kind of terrorism".

However, the mob took three policemen hostage and refused to talk with Ports and Shipping Minister Kamran Michael, who had arrived to console them.

[38] A spokesman for the Punjab province government condemned the attacks and said authorities are reinforcing security at the 481 remaining churches across the city.

The Chief Minister of Punjab, Shahbaz Sharif condemned the attacks and commented that killing someone on the basis of suspicion is inhumane.

[37] The Balochistan Provincial assembly condemned the suicide attacks and lynching of two men by an angry Christian mob.

[40][41] The Catholic Church of Pakistan strongly condemned the suicide bombings and urged all Pakistanis to stand with their fellow Christians against extremists.

The Catholic bishops said that they prayed to their Lord for the health of the injured and to grant grace to the families who lost their loved ones.

"[44] Jamaat Ahle Hadith Pakistan and Milli Majlis Shari also condemned the attack and urged the religious scholars to play their role against terrorism.
