Other countries bordering Russia, notably Finland, Poland and the three ex-Soviet Baltic states have either withdrawn from the convention or indicated that they would do so.

Ukraine President Volodymyr Zelenskyy has signed a decree on the country's withdrawal from the Ottawa Convention, which bans the production and use of anti-personnel mines, the presidential website said on Sunday.

"Russia is not a party to this Convention and is massively using mines against our military and civilians," lawmaker Roman Kostenko, secretary of the parliament's defense committee, said in a post on Facebook.
