NEW DELHI, (REUTERS) – 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 defense industry officials, as well as a Reuters analysis of commercially available customs data.

A dozen other people were injured, some seriously, in the attack in the city of Sumy, which has come under increased bombardment since Ukraine’s offensive into Russia’s nearby Kursk region.

Over the past few months, Kyiv has grown in confidence and ambition as it has ramped up drone attacks inside Russia. It’s struck as far as 1,800km (1,118 miles) in the past, when a long-range radar was hit in the city of Orsk.
