Why has India arrested US, Ukrainian nationals under ‘anti-terror’ laws?

India has arrested six Ukrainian nationals and one American under anti-terrorism laws after they allegedly crossed the border into Myanmar to train armed groups in drone warfare. The detentions represent a rare instance of India invoking stringent counterterrorism statutes against Western nationals, signaling New Delhi's concern about foreign involvement in regional militant activity. The case underscores tensions between India and armed groups operating across its eastern borders, particularly in Myanmar where various militias have grown increasingly sophisticated in their military capabilities. India's move also reflects broader friction over foreign actors' roles in conflicts along its periphery, an area where New Delhi jealously guards its security interests. The detained individuals' alleged mission to provide drone training suggests armed groups are actively seeking advanced military expertise to enhance their operational capacity.
