A week after the American recognition, Sallal boasted at a military parade the republic had rockets that could strike "the palaces of Saudi Arabia", and in early January the Egyptians again bombed and strafed Najran, a Saudi Arabian city near the Yemenite border. The US responded with another aerial demonstration over Jeddah and a destroyer joined on January 15. The US reportedly agreed to send antiaircraft batteries and radar-control equipment to Najran. In addition, Ralph Bunche was sent to Yemen, where he met with Sallal and Egyptian Field Marshal Abdel Hakim Amer. On March 6 Bunche was in Cairo, where Nasser reportedly assured him that he would withdraw his troops from Yemen if the Saudis would stop supporting the royalists.
