One Russian Embassy employee was shot dead in an attack in Baghdad June 3 and four others were kidnapped before being executed by an al-Qaeda linked cell.
"We have experienced ourselves what others experienced before," Sergei Prikhodko said. "Unfortunately, our diplomats were neither the first nor the last victims of what has been unleashed there."
Prikhodko said Russians now understood better what was happening in Iraq after the killings, but said the nation was resolved to continue its efforts.
"We will not lose our nerve or desire to make our contribution - with account for our capabilities - to stabilization of the situation in that country," he said.
