Britons in Lebanon are calling for UK evacuation flights as the country faces shelling and potential ground invasion by Israel. Many British nationals in Lebanon have been unable to leave the country despite their efforts. International airlines have stopped flying in and out of the country's only commercial airport, leaving limited options for evacuation. Some individuals are considering evacuating via sea to Turkey. The situation is causing fear and concern for British nationals living in Lebanon, particularly those in areas that have been targeted by Israeli strikes.
