AFP reports: Aid agencies said Tuesday they were ready to truck desperately-needed supplies to 2.9 million more Syrians after the UN Security Council finally passed a resolution backing cross-border convoys.

“UN agencies have supplies ready to go to all of those hard to reach areas. They had those in place for some time,” Amanda Pitt, spokesperson for the UN’s humanitarian aid coordination arm, told reporters.

The United Nations estimates that 10.8 million people — or half the pre-war population — need aid in Syria, many in areas cut off by fighting.

Reuters adds: The U.N. World Food Programme rushed on Wednesday to put monitors at Syrian border posts, and the U.N. children’s agency UNICEF had aid ready for the first convoys to cross into rebel-held areas under the authorization of the U.N. Security Council.
