Senator Lindsey Graham on Sunday accused Iran of involvement in the Oct 7 Hamas onslaught that triggered a Gaza counter-offensive by Israel, and warned that any escalation of the war could exact a cost from Tehran.
"We're here today to tell Iran: 'We're watching you. If this war grows, it's coming to your backyard,'" Graham said during a visit to Tel Aviv, without elaborating on what that meant.
"The idea that this happened without Iranian involvement is laughable," he said.
