A bomb fell from an Iraqi Sukhoi warplane and exploded in eastern Baghdad on Monday because of a "technical problem", killing at least seven people, security and medical officials said. "One of the bombs became stuck because of a technical problem, and during its (the aircraft's) return to base it fell on three houses in Baghdad Jadida," security spokesman Brigadier General Saad Maan said in a statement. The jet was coming back from a bombing run when the accident occurred, Maan said.
