MOSCOW:  Some 1,400 people, including 700 army and security officials, have been killed in the violence in Syria, a top aide to President Bashar al-Assad said Monday.

"There are 700 casualties among the army and the police, and 700 among the rebels," Assad's media adviser Bouthaina Shaaban said on a visit to Moscow, dismissing a toll of 2,600 people reported earlier by the UN human rights chief Navi Pillay.

"We have a list of (the victims' names), and we can provide it," Shaaban said following talks with Russia's upper house of parliament's foreign affairs chief Mikhail Margelov.

Her comments came moments after Pillay revised the death toll recorded by the United Nations from the conflict up from 2,200 to 2,600 people.

"With regard to Syria, let me note that, according to reliable sources on the ground, the number of those killed since the onset of the unrest in mid-March 2011 in that country, has now reached at least 2,600," Pillay told the UN Human Rights Council.
