Moldovan riot police have regained control of the president’s office and parliament building after they were ransacked by protesters claiming last weekend's elections were rigged.
Anti-communist demonstrators have been protesting outside the Moldova parliament building.
Witnesses in the capital, Chisinau, said an estimated 100 riot police surrounded the buildings early on Wednesday, but not before protesters had stormed them, setting fire to furniture and tossing computers out of the windows.
Interior Ministry spokeswoman Ala Meleca said police arrested 193 people on charges of hooliganism and robbery, following the protests against the ruling Communist Party's victory in weekend elections.

Opposition calls for a recount of the vote were dismissed by Russian Foreign Minister Sergei Lavrov, who said the demands were “absolutely groundless.”
Lavrov stressed that international observers from both western European bodies and a bloc of former Soviet states led by Russia had endorsed the Moldovan vote in a rare display of unity. The OECD observer mission said the vote had been free and fair.
Referring to the “abundance of Romanian flags” used by protesters, Lavrov also cautioned the European Union against trying to exploit the situation in Moldova. Europe's poorest country had been part of EU member Romania until World War II, when it was annexed by the Soviet Union.
Moldovan President Vladimir Voronin accused Romania on Wednesday of being complicit in the mass demonstrations of up to 20,000 mainly youthful protesters. Voronin declared Romania's ambassador “persona non grata” and ordered him to leave Moldova.
