The remains of a Bulgarian soldier killed in a bomb attack in Iraq were flown back to Sofia on a military plane and will be buried later on Thursday. Sgt. Vladimir Pashov, 35, was killed and three other soldiers were wounded on Sunday when a car bomb exploded near their military convoy in the southern Iraqi city of Karbala. Bulgarian Defense Minister Nikolai Svinarov _ who made a brief visit to Iraq on Wednesday _ accompanied Pashov's remains back to Bulgaria.
