Lithuania’s president has said she is considering whether to expel Russian diplomats over the nerve-agent attack on an ex-Russian spy in Britain on March 4.

The UK has expelled 23 diplomats over the poisoning attack on a former Russian double agent and his daughter in Salisbury.

It blames Moscow for the military grade nerve-agent attack which has left both Sergei and Yulia Skripal in critical condition.

Asked whether Lithuania would take similar action, Lithuanian President Dalia Grybauskaite said: “We are considering such measures.”

At a European Union summit Thursday in Brussels, Ms Grybauskaite also offered her full support to British Prime Minister Theresa May.

Former Soviet state Lithuania shares a border with Russia’s western Kaliningrad exclave.
