  • Russia hasn't fulfilled a weapons delivery contract, India says.
  • India says the Ukraine war meant Russia was unable to export the weapons it ordered. 
  • Russia has long been a major arms exporter, but is now struggling to supply its own army in Ukraine.

Russia failed to supply weapons it had been contracted to deliver because of being embroiled in the war in Ukraine, according to the Indian military, one of the Kremlin's main customers.

The Indian Air Force disclosed this week to its parliament that a "major delivery" contracted from Russia would not be showing up.
