1. It’s been a tumultuous 24 hours in Hong Kong, and the coming hours could be telling.

After Monday’s daylong protests, hundreds of riot police used tear gas after midnight to disperse a small group of protesters who had broken into, occupied and vandalized the city’s legislative complex for three hours. Some raised a British colonial-era flag in a repudiation of Chinese rule.

The city’s leader, Carrie Lam, condemned the acts in an early-morning news conference. The escalation has shocked many in the city, divided the protest movement and raised fears that Beijing will use it as justification to tighten control.
