A Czech court on Tuesday released prominent Syrian Kurdish leader Saleh Muslim, who was detained at the weekend and is wanted by Turkey on terror charges, his lawyer said.

"The judge released my client," lawyer MiroslavKrutina told reporters.

He said Muslim has vowed to participate in all extradition proceedings requested by Turkey.

The former leader of the Syrian Kurdish Democratic Union Party (PYD) is still a figurehead for Kurds in Syria.

Earlier on Tuesday Turkey said Muslim's case was a "day of reckoning" for the Czech Republic, pressing its NATO ally Prague to extradite him to face a terror trial.

The arrest came as Turkey presses an over month-long operation inside Syria aimed at dislodging the People's Protection Units (YPG) -- the military wing of the PYD -- from the Afrin region of the country's north.

Ankara sees the YPG and PYD as the Syrian branch of the Kurdistan Workers' Party (PKK), which for over three decades has waged an insurgency against the Turkish state and is banned by Turkey, the US and the European Union as a terror group.

Muslim is wanted by Turkey in connection with a deadly attack in Ankara in February 2016. He has denied any involvement.

Czech Prime Minister Andrej Babis declined Tuesday to comment on the case insisting that "it's a Czech court that decides, I do not know this case, I can not express myself."
