UNITED NATIONS (AP) — Western and Arab nations supporting a U.N. Security Council resolution demanding immediate access everywhere in Syria to deliver desperately needed humanitarian aid are calling for a vote this week, even though diplomats say Russia is opposed to key provisions including a pledge of “further steps” for non-compliance.

Supporters late Wednesday said the resolution had been put in its final form, with a vote likely on Friday. It is unclear whether Moscow will veto the resolution or abstain in the vote.
