The National Democratic Alliance government is carefully dealing with the Islamic State (IS) issue, union Minister of State for Home Kiren Rijiju said on Friday."After our government came to power (in May 2014), we have been dealing with the issue carefully. We have already registered six cases, made many arrests and launched investigations," Rijiju said when asked about a recent IS video that showed Indian-origin terrorists threatening an attack.A multi-tier system had been put in place to ensure the safety and security of the Indian coastline, Rijiju said."The coastline is secure. We have created a subsidiary multi-agency system wherein central intelligence agencies will work in a seamless manner for proper information sharing," he said.The minister is visiting Goa as part of the NDA government's outreach programme on the completion of two years in power at the Centre. "A large number of Muslims in India do not support IS activities. The religious leadership of the Muslims has come out strongly to condemn the IS attempt to lure Indian youths," Rijiju said.Asked about media reports on arms training to Bajrang Dal activists at a camp in Ayodhya in Uttar Pradesh, the union minister said the camp was only providing "self-training".
