LONDON, July 21 (Reuters) - Shipping companies should not load or discharge cargo at Saudi Arabian ports and such activity may result in being targeted "in any location" by Yemen's Iran-aligned Houthi militia, according to an email sent to companies by the Houthis.
The Houthis on Monday declared a naval blockade against Saudi Arabia, opening a potential new front against the United States in its war with Iran and raising the threat to global energy supplies and trade beyond the Gulf.
