Pro-Russian militants and firemen run away as they leave the Regional State building they seized during a shoot-out with Ukrainian border guards defending the Federal Border Headquarters building in the eastern Ukrainian city of Lugansk on June 2, 2014. Ukrainian forces killed five rebels on June 2 while repelling an attack by 500 pro-Russian gunmen on a federal border guard camp in the strife-torn separatist east, Kiev officials said. The border guard service said seven of its servicemen were wounded when “around 500 terrorists” attacked one of its units stationed outside the industrial city of Lugansk. AFPPHOTO/ ALEX INOY
