New Delhi, May 10 -- India has redoubled efforts for listing The Resistance Front (TRF), a front for the Lashkar-e-Taiba (LeT) that claimed the Pahalgam terror attack, as a terror organisation by the UN Security Council to increase pressure on Pakistan, people familiar with the matter said. Efforts for sanctioning the TRF, which were already underway, have gained urgency following the heightening of tensions between India and Pakistan in the aftermath of the Pahalgam attack of April 22 that killed 26 civilians, the people said on condition of anonymity. Indian officials are not buying TRF's efforts to distance itself from the attack after initially claiming responsibility last month, with foreign secretary Vikram Misri saying the group was asked "to back off from this claim" by its handlers in Pakistan once they realised the gravity of the situation. In recent years, India has worked with its strategic partners in the UN Security Council, mainly the US and France, for listing several Pakistan-based terrorist groups and individuals, including leaders of the LeT and proxies for the terror organisation founded by Hafiz Saeed. "The efforts for listing the TRF have been on for some time. We will provide more information to give a fresh push for the listing," one of the people cited above said. India provided inputs about the TRF's role as a proxy for Pakistan-based terror groups in half-yearly reports to the monitoring team for the UN's 1267 Sanctions Committee in May and November 2024. Before this, the monitoring team was informed by the Indian side in December 2023 about the LeT and Jaish-e-Mohammad (JeM) operating in Jammu and Kashmir through groups such as the TRF. "We are going to be meeting with the [monitoring] team again very soon and we will be providing an update to the information that we have provided earlier," Misri told a media briefing on Thursday....
