Official sources believe that over 2 kilograms of RDX, six tiffin boxes with IEDs, and seven detonators dropped by Pakistani drones over the last two years are behind the recent spike in attacks in Punjab.
As many as 37 drones were sighted by the Punjab Police and border guarding forces this year will the ranges from 2 to 10 Km on the international border, according to the data available with the Punjab government.
National Security Guard and National Investigation Agency forensic experts are investigating the blast at the Ludhiana court. Preliminary reports suggest that the person killed in the blast might have been carrying the explosives.
In addition to sharing a border with Pakistan of 553 kilometers, Punjab is also close to the major heroin producing area of golden crescent, which is made up of Pakistan, Afghanistan, and Iran. Efforts by law enforcement agencies to prevent drug smuggling from Pakistan through the land routes in Punjab, India, and then to western countries, have been a point of concern.
