Western nations are expressing concern about an International Atomic Energy Agency (IAEA) report that says Syria has violated its nuclear non-proliferation obligations.
US Ambassador Susan Rice said her country's concerns were confirmed in the report delivered by the IAEA on Thursday to a closed Security Council meeting.
The IAEA said Syria has refused to cooperate with an investigation of its alleged secret nuclear activities.
Syrian UN Ambassador Bashar Ja'afari told reporters outside council chambers that the charges of non-cooperation were unfounded.
French Ambassador Gerard Araud said in a tweet from France's UN mission Twitter account that "Syria has violated its nuclear non-proliferation international obligations".
