RSS chief Mohan Bhagwat today said that any decision on Rohingya crisis should be taken "keeping in mind threat to national security", stressing that Rohingyas are being driven out of Myanmar mainly due to their continuous violent and criminal separatist activities and linkages with the terrorist groups. "We have been facing the problem of illegal Bangladeshi migrants and now Rohingyas have infiltrated into our country. Any decision regarding Rohingyas should be taken by keeping in mind the threat to national security," Mr Bhagwat said, referring to the people who have fled from violence-hit Rakhine state in Myanmar. He was speaking at the Rashtriya Swayamsevak Sangh's traditional annual Dussehra Day rally in Nagpur.
