What are the protests about?
Protesters are demanding the resignation of President Dina Boluarte, who came to power after former President Pedro Castillo was impeached. The former president is currently in pre-trial detention.
Demonstrators are also demanding Castillo's release. Castillo had attempted to pre-empt a vote of no confidence in December by dissolving Congress, after which the legislative body removed him from office. He was arrested on charges of orchestrating an attempted coup.
In December, several airports in Peru were forced to suspend operations following protests.
