Russia denied any involvement in poisoning the former Russian agent Sergei Skripal and his daughter in a United Nations Security Council meeting on Thursday.

During the meeting, which was requested by Moscow, the Russian ambassador to the UN, Vassily Nebenzia, reiterated that “Russia has nothing to do with poisoning Skirpal” and his daughter. “Moscow wants to know the truth more than anyone else,” he added.

The UK accused Russia of poisoning Skirpal and his daughter Yulia in their apartment in the English city of Salisbury and a diplomatic crisis emerged between Russia and the UK, where the latter was supported by 19 EU countries and other allies who expelled Russian diplomats.

Nebenzia condemned what he called a “systematic campaign” against his country, saying that it aims to defame Russia. He demanded answers to why his country was accused of the crime without any evidence and why the UK had not allowed Russia to contact the victims, who are Russian citizens.

Thirty two days after the attack, Yulia released a statement through the Metropolitan police claiming she was getting better, the Guardian reported on Thursday.
