Sweden says it has summoned the Russian ambassador over an air space violation by two Russian military aircraft.

The Swedish Foreign Ministry said the planes crossed into Swedish air space south of the Baltic Sea island of Oland on Wednesday. The ministry called it a "serious violation."

Swedish newspaper Expressen first reported the incident, saying the planes were Sukhoi Su-24 combat planes that left Swedish air space when a Swedish Air Force fighter approached.
