Yemen shut its major seaports, industry and local sources said, after neighboring Saudi Arabia and Arab allies launched military operations including air strikes against Iran-allied Houthi forces fighting Yemen's Western-backed president. "All major seaports were shut down due to the rising conflict," said an industry source. Local sources in Yemen confirmed the closure. Yemen exports about 1.4-1.5 million barrels of Masila crude each month, mainly to China. The ports closed include Aden, Al Mukalla, Al Mokha and Al Hudaydah, the sources said, giving no further details. The majority of Yemen's oil production is located in the north of the country, while the rest comes from the southern area of Shabwa. French oil company Total is the biggest foreign investor in Yemen and operates the Balhaf gas export facility, which mainly exports natural gas to Asia and Europe. (Reuters)
