On a clear day, the dome of Gurdwara Dera Baba Nanak in Gurdaspur is visible from the rooftop of Gurdwara Sri Kartarpur Sahab in Pakistan. It would be, naturally, tempting for Pakistan to eye Gurdaspur as a soft target.
Geographically, Gurdaspur is vulnerable to infiltration. On paper, anybody willing to enter the town from Pakistan would just have to navigate the Ravi and cross into adjoining Dinanagar, the third largest municipality of Gurdaspur and erstwhile summer capital of Maharaja Ranjit Singh. This is the route terrorists currently holed up inside a police station in Dinanagar seem to have taken.
Intelligence sources claim a team of terrorists left Narowal, a small town in Pakistan just a few kilometres from Gurdwara Kartarpur Sahab, on 25 July to strike in India. Just before dawn on Monday (July 27), a group of four to five of them hijacked a white Maruti car at gunpoint near Dinanagar, fired at people at a bus stand and stormed a police station, killing at least nine persons, including a Superintendant of Police. They threw bombs on a railway track and fired at a bus. The casualties could have been more if they had not missed a train by just five minutes or the bus driver had not sped away.
If the terrorists entered India through Punjab, it is an alarming development. The nearly 460-km international border in Punjab is virtually impregnable because of barbed fence and floodlights. Since 1993, when the fencing was completed by India, there has been not a single major incident of cross-border terrorism in Punjab.
The closest the terrorists had come to Punjab before this was in 2014, when a Hizbul Mujahidin terrorist was held at Chakki Bank railway station in Pathankot. The same year, a letter was sent by the LeT to the station superintendant of Pathankot warned of attacks on the Punjab CM and his deputy.
So, it is important to know how the border was breached. Did the terrorists dig a tunnel -- smugglers are known to do this -- and get inside India? Or, did they get unchecked into Punjab through Jammu and Kashmir via the Lakhanpur border, just a few kilometres north of Gurdaspur? Both scenarios indicate serious breach of security and barriers.
Dinanagar is on NH-15 that connects Pathankot in the north and Samakhiali in Gujarat. If terrorists from Pakistan have found a way to get into Dinanagar, the entire 1526-km highway is vulnerable to future attacks. So, the first challenge for India would be to ensure that the border is sealed.
The other worrying development is that terrorists now have their eyes on Punjab; they are trying to open a second front after J&K. The north Indian state has been quiet for almost two decades. The Gurdaspur incident will revive memories of the state's struggle with terrorism in the 80s.
