Russia has summoned Poland’s ambassador to issue a note of protest over Monday’s nationalist attack on the embassy in Warsaw during a so-called ‘independence march’.

The nationalist march escalated into an attack by demonstrators on Russia’s embassy.

The Russian Foreign Ministry accused Polish police of failing to protect the diplomats from “rampaging brutes,” calling the incident a gross violation of Vienna Convention on Diplomatic Relations, which demands the host country ensure the safety of diplomatic staff of a foreign embassy.

Russia noted the “the passive and late response of the police, which played a major part in allowing the rampage of the unruly brutes,” the ministry said in a statement.

The outraged response comes a day after the evening attack, in which a crowd of Polish nationalist pelted the Russian embassy with flares, bottles and other projectiles.
