Saudi Arabia has bombed Yemen’s port city of Mukalla, targeting a shipment of weapons from the United Arab Emirates for separatist forces. This move threatens to bring new risks to the Persian Gulf region. The UAE-backed Southern Transitional Council recently seized parts of Hadramout and Mahra provinces, including oil facilities. Yemen has been embroiled in a civil war for over a decade, involving regional powers like Saudi Arabia and the UAE. The conflict has created a humanitarian crisis and shattered the economy. The recent escalation highlights strained ties between Riyadh and Abu Dhabi, who have backed competing sides in Yemen's war.
