Police in Russia arrested nearly 1,700 people at anti-war protests staged in 53 cities across the country. Al Jazeera reports that a petition, started by a prominent human rights advocate, garnered over 150,000 signatures within several hours and 289,000 by the end of the day. More than 250 journalists put their names on an open letter decrying the aggression, and another one was signed by some 250 scientists, while 194 municipal council members in Moscow and other cities signed a third. Several Russian celebrities and public figures, including some working for state TV, also spoke out against the attack.
