US closely monitors Iran as it accelerates defense pact with Saudi Arabia

Biden: 'Iran is actively facilitating rocket and drone strikes into Iraq'

Bilateral security agreement raises concerns as tensions heighten in the region

The United States is closely monitoring developments in Iran as it accelerates a defense pact with Saudi Arabia, according to US officials. The bilateral security agreement raises concerns as tensions heighten in the region.

Two US officials told the BBC's US partner CBS News that an Israeli missile struck Iran overnight. Iran has denied the attack, but the US officials said it was part of a pattern of Israeli strikes on Iranian targets in recent months.

The US has also accused Iran of actively facilitating rocket and drone strikes into Iraq. President Joe Biden said Sunday that the US "will continue to counter Iran's destabilizing activities in the region."

The White House on Monday said Iran was "in some cases actively facilitating rocket and drone strikes into Iraq." The US has also accused Iran of providing weapons and training to Iraqi militias.
