Residents of Aden heard explosions before Yemen's Houthis ordered the immediate evacuation of the city's international airport, Reuters reported. A second warning appeared less than two hours after the first, according to Anadolu. Houthi military spokesman Yahya Sari claimed that a Saudi military cargo plane carrying weapons was at the airport. This claim has not been verified. Saudi authorities have not responded, and no attack at the airport has been confirmed.
