The Polish government has convened crisis talks following reports that a Russian missile intended for a Ukrainian power station has landed in the Nato member country, killing two people.
A US intelligence official has told the Associated Press news agency that missiles landed across the Ukraine-Poland border during an assault on Ukrainian energy facilities. Polish officials are now considering whether to call for wider Nato discussions under Article 4 of the military co-operative's founding treaty.
The clause allows member states to call for discussions on whether "the territorial integrity, political independence or security of any of the parties is threatened". Polish government spokesman Piotr Mueller did not immediately confirm the information from US officials, but said top leaders were holding an emergency meeting due to a "crisis situation."
