On 27 July 2015, three gunmen dressed in army uniforms opened fire on a bus and then attacked the Dina Nagar police station in Gurdaspur district of Punjab, India. The attack resulted in the death of three civilians and four policemen, including a superintendent of police; fifteen others were injured. In addition, five bombs were found planted on the Amritsar–Pathankot line on a rail-bridge near Parmanand railway station, five kilometers from the site of the attack. All three attackers were killed in the operation, which lasted almost 12 hours.Such terrorist attacks are rare in Punjab after the Punjab insurgency, which sought to form an independent Sikh nation of Khalistan, ended in the 1990s. However, such attacks are common in the Disputed Territory of Jammu and Kashmir that borders Gurdaspur, where Islamist insurgents are seeking independence or accession to Pakistan and from where the gunmen were at first suspected to have entered. On the basis of the GPS system found in the terrorists' possession, it was found that they entered India through Pakistan.
