Venezuela’s Supreme Court sentenced on Tuesday an opposition mayor to 15 months in jail, as the government continued its crackdown on the opposition.

The mayor, Ramón Muchacho, who led the wealthy Chacao district in Caracas, was also stripped of his position and barred from holding public office, according to a statement issued by the judges. The court has also ordered a second opposition mayor, David Smolansky, to appear before it on Wednesday.

The officials, both well-known politicians in their parties, were among 13 mayors who had been ordered by the judges in May to halt anti-government protests that involved erecting barricades to block traffic. The protests continued, with many mayors arguing that residents had a right to peaceful protest under the country’s laws.

The court has sentenced at least three other mayors to 15 months in jail for failing to comply with the court’s order. The others include Gustavo Marcano of Lechería, Carlos García of Mérida and Alfredo Ramos of Barquisimeto, a large city in northwestern Venezuela.
