"As a Signatory State of CWC [Chemical Weapons Convention] and a member of OPCW [Organisation for the Prohibition of Chemical Weapons], we strongly condemn any use of chemical weapons. It is in the interest of the international community to conduct a through investigation of the attack in Salisbury, in which all sides would constructively cooperate, including the Russian Federation. Those responsible should be brought to justice," the press office said.
The Foreign Ministry noted that Slovenia was in close coordination with its EU partners regarding the further steps in the light of the answers provided by the Russian authorities.
"We remain closely focused on this issue," the press service added.
The UK side claimed that this substance was related to the Novichok-class nerve agents developed in the Soviet Union. UK Prime Minister Theresa May has accused Russia of orchestrating the attack and expelled 23 Russian diplomats as a punitive measure.

Earlier in the week, EU leaders said at a Brussels summit that they had agreed with London that Moscow was "highly likely" involved and ordered the bloc’s ambassador to Russia to return for consultations.
Several EU countries, including Estonia, Latvia, Ireland and the Czech Republic said they were considering the expulsion of Russian diplomats over the incident.
The Russian side has strongly rejected the accusations and offered assistance in the investigation. However, Moscow's request for samples of the chemical substance used to poison Skripal was denied. Moscow also expelled UK diplomats and ordered the British Council to stop its activities in Russia in response to the UK move.
