The four personnel belonging to Indian Reserve Police-3rd battalion were on law and order duty in the township in north Kashmir, 50 km from here, when the IED planted by militants in the market, which was shut due to a separatist-sponsored strike, went off, police said.
Jaish-e-Mohammad (JeM) militant outfit has taken responsibility for the attack, but the Kashmir police said it will have to verify the claim.
The slain personnel were identified as assistant sub-inspector (ASI) Irshad Ahmad - a resident of Doda, Constable Ghulam Nabi - a resident of Rohama Rafiaabad area of Baramulla, Constable Parvaiz Ahmad - a resident of Vilgam, Handwara and Constable Mohammad Amin - a resident of Sogam, Kupwara.
Additional Director General of Police (ADGP) Munir Khan said the use of IEDs by militants had ended since 2015 and the security forces will have to chalk out a new strategy in the wake of the blast.
These young policemen were killed when they were on duty to protect the people in the town. It is highly unfortunate, Mufti said.
Former chief minister Omar Abdullah tweeted: "Very sad news from #Sopore. May the four brave J&K police personnel killed in the line of duty today rest in peace."
J-K Congress chief GA Mir condemned the killing and claimed the incident had exposed the "tall claims" of the Mehbooba government about the Kashmir situation being normal.
"Our normal law and order deployment reached the lane between Chotta Bazaar and Bada Bazaar. There was an IED blast in which four of our boys were martyred," said Khan, who was recently promoted as additional director general of police, but continues to hold the post of inspector general of police (IGP) Kashmir.
"The IED was placed beneath the entrance of a shop. It was a big IED, there has been a huge crater because of it. Six or seven shops have suffered damage as well," he said, adding "it was the first (IED) blast since 2015. Its use had almost ended."
He said the security forces will have to think about it. "We will put our heads together and chalk out some new strategies to tackle this thing, he said.
The JeM, in a statement to a local news agency here, claimed responsibility for the attack.
But Khan said, "We will have to verify how authentic the statement is. A mere statement does not mean that only they have done it. We will have to see other aspects also.
A wreath-laying ceremony was held at District Police Lines Sopore to pay homage to the slain personnel.
Khan led police officers and jawans in paying floral tributes to the martyrs, a police spokesman said here.
The spokesman said ASI Irshad Ahmad is survived by his elderly mother, wife, two sons and two daughters.
Constable Mohammad Amin leaves behind an aged mother, wife, four-year-old son Tajam-ul-Islam, a brother and three sisters, while constable Parvaiz Ahmad is survived by an elderly father, wife, three-year-old son Mohammad Noman, an unmarried sister and three brothers, the spokesman said.
He said constable Ghulam Nabi has aged parents, pregnant wife, four-year-old daughter Faheeqa Nabi, two brothers and two unmarried sisters.
