The WSJ has some action on the meeting:

The NSG talks Friday began constructively with delegations split between those that would accept a revised draft of a resolution text, and those that wanted tough language that would permit conditional nuclear exports to India, according to a diplomat familiar with the discussion. Additional changes Friday morning and afternoon brought more delegations on board, but not all, the diplomat said.

In the late afternoon the delegates reconvened in an unusual evening session for what they hoped would be one last push to agree on a new revised resolution text, according to a diplomat with knowledge of the discussion.

About 8:00 pm the delegations were still far apart and split into smaller working groups, in the hope of later meeting again in full session for a final decision. During the evening, the U.S. intensified its diplomatic effort in a series of phone calls, one diplomat said.

At 2:00 am and still without agreement, the meeting adjourned until 11:00 am when delegates returned to approve a resolution.

Good times…
