 A missile attack on Ukraine's occupied Mariupol city has killed over 250 Russian troops just a week after 200 Russia soldiers were killed in the same city, Russian telegram channel Kremlinovsky at Tabakurka reported on Saturday. Ukrainian missiles hit the area where a large number of troops and military equipment were gathered, the channel said with reference to an unknown source within the general staff of Russian armed forces. The attack targeted experienced military personnel, special forces and Marines who arrived in Mariupol on May 25, the day before the strike, the channel said. Many locals hate us here. They are following us, aiming missiles at us, waiting for the Ukrainian army. It's unbearable here, the source said. The source ruled out the attackers will be found. Yet another source told the telegram channel that Russian troops must be withdrawn from Mariupol and concentrated on protecting more important regions such as Crimea, Kostov, Belgorod, Bryansk and other regions bordering Ukraine.
