Official media say arrests have been made following massive anti-government protests in an eastern Chinese city hit by catastrophic flooding.

Photos from the scene showed protesters smashing vehicles and attacking city offices during Tuesday's protest in Yuyao. Hundreds of riot police were massed in front of city hall.

The official Global Times newspaper said Wednesday thousands had taken part in the protest and that an undisclosed number were arrested. It said residents were angered over an allegedly botched response to the flooding and the slow restoration of services.

City officials on Wednesday either said they had no information or did not answer phones.

Provincial official Cai Qi called on his microblog for a rational response to the flooding, and said officials had been working all-out to deal with the disaster.
