Indian investigators have arrested seven foreigners, including six Ukrainians and an American, on suspicion of illegally crossing into neighbouring Myanmar to train armed militia groups, the public radio broadcaster reported on Tuesday.

Myanmar descended into civil war after a junta seized power in a 2021 coup, with pro-democracy guerrillas and ethnic-minority armed groups fighting for control of large parts of the country.

India has long been suspicious of certain Myanmar factions that have the same ethnicity as populations on the Indian side of the border, fearing a spillover of violence and unrest.

On Monday, a closed court in New Delhi remanded the seven foreign nationals in custody for 11 days of interrogation after they allegedly illegally entered sensitive Mizoram state without an official permit, All India Radio (AIR) reported.
