Iran shrugged off a plea by Russia's Foreign Ministry that it comply with UN demands to limit its nuclear program after Monday's passage of new sanctions against the Islamic republic. On the other hand, objections by Russia and China caused the International Atomic Energy Agency to drop plans for a resolution that would apply more pressure on Iran on top of the latest sanctions. Sources quoted the opponents as saying the IAEA "doesn't need to compete" with the UN Security Council.

Feuding between Russia and Ukraine over the flow of natural gas appeared to be coming to a head. The former's gas utility warned that it "reserves the right" to divert fuel sent by pipeline to western Europe for its own needs if there's a further cut in its supply.

At least two soldiers were reported dead in fighting Tuesday between Armenia and Azerbaijan over the disputed territory of Nagorno-Karabakh. The ex-Soviet republics have observed an uneasy truce since 1994 after an estimated 35,000 people died in a war to end Azeri rule over the majority-Armenian enclave. But tensions have risen due to parallels with the declaration of independence in Kosovo. Azeri President Ilham Aliyev said his government was buying "military machinery and ammunition ... to liberate" Nagorno-Karabakh.
