Lebanon has banned pagers and walkie-talkies on all flights departing from Beirut following explosive attacks by Israel. Passengers are prohibited from carrying these devices in both checked and carry-on luggage, and the ban also extends to air shipments. The ban comes after two waves of deadly explosions involving Hezbollah militants' pagers and walkie-talkies across Lebanon, Syria, and Iraq. Hezbollah leader Hassan Nasrallah called the attacks a 'declaration of war' and dared Israel to invade Lebanon. Israeli forces responded by carpet bombing Hezbollah strongholds in southern Lebanon.
