BEIJING (AP) — Police said Monday they detained 60 people following a protest over plans to build a waste incinerator in a city in eastern China, where neighbors expressed skepticism about official pledges to seek public approval before proceeding.

Officials repeated in state media that they would seek public support for the incinerator even as they pursued the arrests of more than a dozen people behind weekend protests in Hangzhou involving thousands of people. At least 10 demonstrators and 29 policemen were injured and protesters blocked a major highway.
