Krzysztof Szczerski, Poland's ambassador at the UN, warned in a UN General Assembly address on Wednesday that Russia's aggressive actions in Ukraine may spark a huge security crisis.

Russia officially recognised Ukraine's two breakaway eastern provinces on Monday and the West fears that the conflict may spill to other countries. The EU, Great Britain and the US reacted with new sanctions, and Germany halted the opening of a multi-billion euro Russia-Germany gas pipeline.

Szczerski told the General Assembly that the conflict may grow to "unprecedented proportions" and that Russia's actions are a reminder of imperialist times before the establishment of the United Nations.

Szczerski said there could be no return to pre-UN times, including imperialism, colonialism and dominance of some countries over others.
