"To date, as of 8:30 am Moscow time, according to preliminary data, 372,779 people took part in the election, but this is not final data," Zakharova told the Channel One broadcaster.
The last polling stations abroad closed at 02:00 GMT on Monday, so there are no final numbers at the moment, the diplomat said.
Zakharova added that around 90% of ballots cast abroad had been processed, with incumbent Russian President Vladimir Putin ahead of other candidates.
