Thousands of protesters filled the streets in Romania Sunday to oppose plans by U.S. energy giant Chevron to drill for shale gas.
Coordinated anti-fracking protests were held in nearly 60 Romanian cities.
Demonstrators want local control over drilling decisions and more transparency.
They also called for a ban on hydraulic fracturing.
Chevron won exploration permits in northeastern and southeastern Romania after assuring the country it would comply with environmental regulations.
Despite local opposition, Chevron has begun drilling its first exploration well in the village of Pungesti.
Hundred of riot police in December removed protesters who had occupied the drilling site for a couple of months.
