LONDON: Saudi Arabia has emerged as a potential lifeline for other Gulf states who face dwindling stocks of vital medicines the longer the Middle East war goes on. Gulf airspace is constantly disrupted, but Riyadh and Jeddah airports remain open to accept deliveries from pharmaceutical companies. The medicines can then be transported by road to their destination. Other options were Istanbul and Oman. The Gulf relies heavily on imports and some medicines have short shelf lives and need strict cold-chain storage.
