Reports that a communications of a Romanian fighter jet which was on a patrol in the Black Sea went dead. A Romanian helicopter which went to search for it crashed and the 5 men crew supposedly are dead.

The reasons for these two strange events are not clear, or have not yet been reported.

In addition, officials in Sweden say 4 Russian fighter jets violated their airspace recently.

Here is the Reuters report on this:

Four Russian fighter jets briefly entered Swedish territory over the Baltic Sea on Wednesday, the Swedish Armed Forces said, sparking a swift condemnation from Sweden's defence minister.

Two Russian SU27 and two SU24 fighter jets briefly entered Swedish airspace east of the Swedish island of Gotland in the Baltic Sea, Sweden's Armed Forces said in a statement, adding that Swedish JAS 39 Gripen jets were sent to document the violation.

"The Russian violation of Swedish airspace is of course completely unacceptable," Defence Minister Peter Hultqvist told news agency TT. "It will lead to a firm diplomatic response from Sweden. Swedish sovereignty and territory must always be respected."

Sweden's Armed Forces said the situation was under control and that the incident showed preparedness was good.

"In the light of the current situation we view this event very seriously."
