Obviously there are some tensions between the Polish and Russia, mainly coming from the Poles. There are still some bad blood left there from the Cold War. The attack on the embassy isn't the only example of hatred towards the Russians. The Polish ambassador was forced by the Russian Foreign Ministry to issue an apology and compensate them for the damage to their embassy. The ambassador also had a lack of attentiveness when the attack occurred while the police force responded with passivity and lateness. It seems that those brave souls who attacked the embassy aren't the only ones with strong feelings against the Russians. Conflicts such as these have the potential to become more if not handled properly. We will have to wait and see what else happens between the two countries.
