Yet another stowaway managed to board a major airline’s plane – renewing serious questions and concerns about airport safety during the busiest travel season of the year.

This incident comes less than a month after another unticked passenger managed to make it aboard a Delta flight from New York to Paris where they were arrested once the plane landed

A Delta Air Lines flight at Seattle-Tacoma International Airport was involved in yet another stowaway incident. The event, which took place on Christmas Eve, has rekindled concerns regarding airport safety procedures and screening policies.

The head of the World Health Organization said on Friday he was not sure he was going to survive an air strike on Yemen's main airport carried out by Israel a day earlier during a series of attacks on the Iran-aligned Houthi movement.

The Israeli military said it attacked infrastructure used by Yemen's Houthi rebels at the international airport in the capital Sanaa, as well as power stations and ports, alleging they were used to smuggle in Iranian weapons and for the entry of senior Iranian officials.
