Russia has summoned the Polish ambassador to Moscow to the foreign ministry, ministry spokeswoman Maria Zakharova said on Wednesday.
Earlier the Kremlin accused Poland of reacting in "absolutely hysterical" fashion to Tuesday's incident when two people were killed by a missile in eastern Poland. Poland and NATO said on Wednesday it was probably a stray rocket fired by Ukraine's air defences and not, as some reports initially suggested, by Russia.
