Supporters of Hong Kong’s pro-democracy movement lined the streets and part of the city’s harbor front Friday, inspired by a human chain in a historic Baltic states protest against Soviet control 30 years ago. It was the latest protest in a nearly 11-week-old movement that began with calls to scrap a now-suspended extradition bill and has widened to include demands for full democracy and an independent inquiry into alleged police brutality at protests. In a protest dubbed “The Baltic Way,” nearly 2 million Latvians, Lithuanians and Estonians formed a human chain more than 600 kilometers (370 miles) long on Aug. 23, 1989.
