Russia blocks UN resolution to extend aid delivery to rebel-held northwest Syria

The UN Security Council failed to renew authorization for cross-border aid deliveries from Turkey to northwest Syria.
Russia vetoed a compromise resolution for a 9-month extension supported by most members.
Two rival resolutions for aid delivery through the Bab al-Hawa crossing failed to pass.
The aid operation provided critical assistance to over 4 million people in the rebel-held region.
Aid groups strongly criticized Russia's actions and called for renewed efforts to continue assistance.
