Overnight, several waves of Savoia-Marchetti SM.81 bombers attacked the port facilities. On 22 June the Italians suspected the British might try to establish a forward base at Djibouti, and five Ro.37bis, four Fiat CR.42 and one Fiat CR.32 aircraft hit the airfield there. Some French Potez 25 reconnaissance aircraft bombed Italian installations at Dewele in retaliation.
