US to send clear message that it will respond when its forces are attacked

US National Security Advisor Jake Sullivan said in an interview with NBC that the US "intend to take additional strikes and additional action to continue to send a clear message that the US will respond when our forces are attacked and our people are killed".

He added that he believes the strikes had a "good effect" on degrading militia groups' capabilities.

"We are prepared to deal with anything that any group or any country comes at us with," he said when asked about Iran's threats that US strikes will destabilise the region
