At least 20 people were killed in violent protests against rising living costs in Chile, according to the country’s Justice Ministry.

The ministry said on Tuesday that a total of 1,218 people, including 745 security officers, were also injured since the start of the demonstrations on Oct. 6.

The anti-government protests, which began as a reaction to a now-suspended 4% transport fare hike, turned violent on Oct. 19.

During the unrest, 49 subway stations were destroyed and 26 buses were set on fire. Over 9,200 people were arrested across the country, the ministry added.
