NEW DELHI: The Supreme Court on Monday dismissed a plea seeking a probe into possible larger conspiracies behind the February 14 Pulwama terrorist attack in which 40 CRPF soldiers were killed.The PIL , filed by lawyer Vineet Dhanda, had claimed that nearly 370 kg RDX explosive was used by the Jaish-e-Mohammad (JeM) suicide bomber who rammed his vehicle into the bus carrying the soldiers and hence required a thorough probe.A bench of Chief Justice of India Ranjan Gogoi and Justice Sanjiv Khanna dismissed the plea.The plea had also sought directions to the Centre to constitute a committee headed by a retired judge of the apex court to inquire the role of Indian citizens in the Uri and Pulwama terrorist attacks.It alleged that though the investigations by the Centre and the Army found procedural lapses in the 2016 Uri attack in which 17 jawans died, they did not carry out any detailed investigation because of which the people behind it were not punished.It further claimed that the role of locals in Kashmir, who had allegedly given support to Pakistani terrorists were also not investigated, which gave confidence to JeM to carry out the Pulwama attack
