More than 20,000 protesters on Sunday marched through the streets of the capital Chisinau demanding the resignation of Moldova's pro-European government.

Pro-Russian parties organized the demonstration in a bid to unseat the government led by Prime Minister Valeriu Strelet after it was discovered that over $1.5 billion disappeared from three Moldovan banks prior to 2014's parliamentary elections.

The state-owned Savings Bank, Social Bank and Unibank were placed under the control of the National Bank of Moldova, which covered the losses through state cash reserves, prompting a crisis of confidence among many Moldovans left to foot the bill.

Chanting "down with the thieves," the protesters also called on leaders of a number of state institutions to step down, including the heads of the central bank, attorney general's office and the country's anti-corruption commission.

Police surrounded the buildings of Moldova's institutions, including parliament, in response to the mass demonstrations.

The latest demonstrations come amid a two-week visit by an International Monetary Fund (IMF) delegation, during which the global financial institution said a new loan was unlikely to materialize.

Earlier this month, Moldova's central bank governor resigned in response to previous protests.

The former Soviet nation is considered one of Europe's poorest countries.
