Retirees in the central Chinese city of Wuhan and the northeastern city of Dalian took to the streets last week to express their outrage over the local government¡¯s curtailing of medical insurance coverage.

Photos and videos of demonstrations circulating online show crowds of senior citizens gathering in various areas of the two cities, including a local hospital and park in Wuhan and a public square outside a district government building in Dalian. Some protesters can be heard singing ¡°The Internationale.¡± A heavy police presence is seen in several video clips, but it remains unknown whether police have arrested any protesters as a result of the demonstrations.

Seniors participating in the rallies are protesting against proposed changes to the country¡¯s medical insurance system.
