An estimated 250,000 Colombians took the streets around the nation Thursday in a protest that started off peacefully but ended in scattered clashes.

Duque has promised to begin a “national conversation” aimed at including students, labor unions and other groups in drafting reforms.

Over 330 people were caught violating Friday’s curfew and about 170 detained.
