Pro-democracy lawmakers in Hong Kong heckled the city's embattled leader and called for her to step down on Thursday during a legislative session that was repeatedly suspended as several politicians were manhandled out of the chamber.

It was the second day of chaos in Hong Kong's Legislative Council as Chief Executive Carrie Lam tried to answer questions about her annual policy address, which she was forced to deliver by video link on Wednesday after similar disruption in the assembly.

The turmoil in the legislature underscores the deepening political rift in the city, with no end in sight to the often violent anti-government protests, which began in opposition to an extradition bill but have evolved into a broad pro-democracy movement.
