Protests erupted in 11 Turkish cities Tuesday evening demanding Turkish Prime Minister Recep Tayyip Erdogan to resign as an alleged audio recording of him discussing a plan to hide money from police continues to circulate around the country.

Thousands of people took to the streets in 11 cities of Istanbul, Ankara, Izmir, Antalya, Antakya, Samsun, Trabzon, Eskisehir, Kocaeli, Bursa and Canakkale.

In the recording, Erdogan and his son Bilal allegedly discussed a plan to hide vast amounts of cash in several houses on the day police raided a number of venues in a massive corruption investigation.

The probe has implicated sons of three Turkish ministers, the chief of the state bank and some businessmen.

The prime minister has rejected the allegations, labeling the leaked recordings as "fake." The attorney general of Ankara has made a plea over the recordings.

In Istanbul the protests have been held in 10 different locations. The biggest crowd gathered in Istanbul's Asian district of Kadikoy.

Some 5,000 people shouted anti-government slogans as they marched toward the district center.

Holding banners with slogans like "Where are the thieves," "You will answer to the people," and "Everywhere robbery, everywhere corruption," the anger on the street was visible.

In Istanbul, Bursa and Eskisehir riot police clashed with the protesters.

In Bursa, police tried to prevent the crowd from marching toward the ruling Justice and Development Party (AKP) Headquarters.

In Eskisehir police dispersed protesters by firing water cannons and rubber bullets and in Kocaeli, protesters threw eggs at the AKP's headquarters breaking the windows of the building.
