Members of the US Senate unanimously voted on Thursday in favor of extending 1996 sanctions against Iran for an additional 10 years.

"Senate passed H.R. 6297, the Iran Sanctions Extension Act by a vote of 99-0," Senate Periodical Press Gallery said in a Twitter message. US President Barack Obama is expected to sign the bill, which has already been approved by the US House of Representatives.

On November 15, the House passed the Iran Sanctions Act, which extends sanctions against Iran's weapons programs and ballistic missile development that are not part of the 2015 nuclear agreement.

Under the agreement, some sanctions, including embargoes on gas and oil trade, were lifted in exchange for Iran's compliance with inspections and guidelines to ensure its nuclear program remains peaceful.
