The parliamentary election has taken on wider significance with the unrest in neighboring Ukraine. Moldova, like Ukraine, has a pro-Russia separatist region in its east.
Early results yesterday showed pro-Russian parties with a strong lead. But as more votes were counted, the gap closed.
With 52 per cent of the vote counted, the pro-Europe parties were slightly ahead with about 42.5 per cent to 41 per cent for the pro-Russian parties. Parties need to get at least 6 per cent to gain seats in the 101-member Parliament.
The impoverished former Soviet republic of less than 4 million people is torn between re-electing the current pro-European coalition and choosing parties that want closer economic ties with Moscow.
