SANTIAGO, Chile (AP) — Electricity providers across Chile scrambled to restore service Tuesday after a sweeping blackout plunged 90% of the country into darkness, stranding commuters, knocking cell service offline and paralyzing businesses and daily life.

Most residents had power restored by midnight but the situation remained unstable. President Gabriel Boric blamed power companies for not acting faster.

A large power outage struck most of Chile on Tuesday, resulting in a curfew until Wednesday morning for the areas hit by the blackout.
