Mohammad Salimullah, a Rohingya refugee living in the Indian capital New Delhi, is again living in fear.

Having fled Myanmar more than 14 years ago to escape persecution, Salimullah now lives in a makeshift Rohingya settlement, where he owns and operates a small general store.

"Here, after becoming refugees, we found the right to work, the right to go anywhere we'd like," he said. "The (government in Myanmar) kept us in such a narrow and helpless state," he tells CNN. Now, he worries that his hard-won freedom is under threat.
