Gunfire and blasts were heard again at Pathankot Air Force base which was attacked by militants a day earlier on Saturday as security forces hunted two gunmen still at large in the sprawling facility near the border with Pakistan.Meanwhile, Trains were delayed at New Delhi Railway Station and a Lucknow-bound Shatabdi was evacuated after authorities received a bomb threat early on Sunday morning.A senior federal police official confirmed the gunmen were still holed up in Pathankot air base in Punjab state, a day after the pre-dawn raid in which four attackers and six Indian military personnel were killed.Outside the base, rumours had circulated all morning that more gunmen were still active after Home Minister Rajnath Singh had announced on Saturday that five terrorists had been “neutralised”. The official body count was only four, however. Military vehicles were seen entering and exiting the walled compound, including a demining vehicle. Dozens of security guards continued their vigil, while protesters shouted slogans and burned a Pakistani flag nearby.The attack by gunmen disguised as soldiers came a week after Modi made an unscheduled visit to Pakistani counterpart Nawaz Sharif in an effort to revive talks between the nuclear-armed neighbours.At least two security personnel were wounded in a blast on Sunday, a police official in Pathankot said, as troops scoured the base. One later died, according to reports that could not immediately be confirmed.The breaching of the base’s defences has raised questions about lax security on the international border in Punjab, which is a known route for drug smugglers and is less closely guarded than the disputed frontier running through Kashmir. Most of the Indian military reported killed had retired from active service and belonged to the Defence Security Corps, a unit that staffed by veterans no longer in active service.In New Delhi, two trains were delayed early on Sunday amid heightened security concerns after officials received information about a possible bomb threat on a train running between the capital and Lucknow to the southeast, railways spokesman Neeraj Sharma said.Trains were deemed safe and were running on schedule by mid-morning, Sharma said.Speaking on the bomb scare at New Delhi station, Milind Dumbre, DCP (railways), said: “We have taken all security measures. A search is underway. No suspicious object has been found so far.”
