The Iranian Embassy in India has said it is investigating the case of three Indian nationals who went missing in Tehran earlier this month.

The men, all of whom are from the northern state of Punjab, had a stopover in Iran on 1 May, and were on their way to Australia, where they were promised lucrative jobs by a local travel agent.

Their families allege that they were kidnapped upon their arrival by unknown men, who are now demanding a ransom of 5m rupees ($63,000; £47,000).

On Thursday, the Iranian Embassy said on X that it was keeping Indian authorities informed of all developments "within the judicial system" and warned about the dangers of taking illegal immigration routes.
