This article discusses an incident between the US and Russia, in which a Russian fighter jet harassed and collided with a US MQ-9 Reaper drone, forcing the US to bring it down in international waters. In response, Russia has warned the US to cease “hostile” activity near its border, while the US has called the incident a “brazen violation of international law” and summoned Moscow's envoy to lodge a protest. This is the first known direct confrontation between the two superpowers since the war began last year, and tensions are likely to continue to rise.
