HONG KONG (AP) — Several hundred people who work in advertising in Hong Kong say they will strike this week to support the anti-government protests in the semi-autonomous Chinese territory.

The advertising workers not going to their jobs this week rallied in a public square in the central business district Monday.

Some held up signs with protest slogans as they sat on the ground listening to a series of speakers.

Hong Kong has seen almost nonstop protests for six months demanding democratic elections and an investigation into police use of force at the demonstrations.

Riot officers fired tear gas and pepper-spray balls in clashes with protesters Sunday night.
