Artillery shells sold by Indian arms makers have been diverted by European customers to Ukraine and New Delhi has not intervened to stop the trade despite protests from Moscow, according to 11 Indian and European government and defence industry officials, as well as a Reuters analysis of commercially available customs data.

The transfer of munitions to support Ukraine’s defence against Russia has occurred for more than a year, according to the sources and the customs data. Indian arms export regulations limit the use of weaponry to the declared purchaser, who risks future sales being terminated if unauthorised transfers occur.

The Kremlin has raised the issue on at least two occasions, including during a July meeting between Russian Foreign Minister Sergei Lavrov and his Indian counterpart, three Indian officials said.
