BANGKOK (AP) — At least 42 people have been injured in clashes between police and anti-government protesters in Bangkok after police started rounding up demonstrators who have been camping out at various locations around the capital.

Multiple gunshots were heard midday Tuesday at the site, in a historic section of town near the Government House, but it wasn’t clear who was firing.

Police moved into several protest sites around the city to detain and remove protesters wanting to unseat the prime minister. They have been blocking access to government offices since late last year and occupying key intersections in Bangkok for about a month.

Erawan emergency medical services said at least 42 people have been injured. It was not immediately known if they were protesters or police.
