The conclusion of the document entitled "Barrage deaths: report on Shahed-136/131 UAVs" is that Western components have made their way into construction of Iranian Shahed Kamikaze drones, which Kiev sees as a scandal which must be dealt with.

"A wide range of components produced by western companies have been found in the downed drone models, according to the submission to the G7, which comprises France, the US, the UK, Germany, Japan, Italy and Canada, plus the EU," The Guardian writes, based on the secret document it has reviewed.

The publication attempted to track down some of the Western companies, located across Europe, whose parts are being used by the Iranians to manufacture the drones: 

A fuel pump manufactured in Poland by the German company Ti Automotive GmbH, of which the British multinational TI Fluid Systems is the parent company, was discovered in a Shahed-136, as well as a microcontroller with built-in flash memory and a very low-voltage drop regulator with inhibitor made by the Swiss firm STMicroelectronics, according to the paper.
