Protesters hold a rally to demand the creation of a parliamentarian committee of inquiry to investigate what they say a Ukrainian security service operation to detain Russian mercenaries in Kyiv, Ukraine September 14, 2020. A group of Russians were detained in Belarus prior to its Aug. 9 presidential election and were accused of seeking to destabilise the country. Ukraine sought the extradition of the detainees whom it suspected of fighting alongside Russian-backed separatists during a military conflict in its eastern regions but Belarus later returned them to Russia.
