The United States will seek to strengthen and extend the agreement between world powers and Iran aimed at curbing its nuclear program, Secretary of State Antony Blinken said on Monday.

Blinken, addressing the UN-sponsored Conference on Disarmament in Geneva, said: "Working with allies and partners, we will also seek to lengthen and strengthen the JCPOA (Joint Comprehensive Plan of Action) and address other areas of concern, including Iran's destabilizing regional behavior and ballistic missile development and proliferation."
