Flights from Aden International Airport in Yemen were suspended on Thursday due to ongoing tensions between the Southern Transitional Council (STC) separatist group and the Saudi Arabia-backed, internationally recognized government, according to Reuters. The news agency reported the suspension of all flights, but details regarding the extent of the disruption and potential resumption of operations were not immediately available.

The halt in flights underscores the fragile security situation in Aden, a key port city and the interim capital of the internationally recognized government. The STC, while nominally part of the Saudi-led coalition fighting against the Houthi rebels, has its own agenda, seeking independence for southern Yemen. This ambition has led to frequent clashes with forces loyal to the central government.

The conflict in Yemen has been ongoing since 2015, when the Iran-aligned Houthi rebels seized control of the capital, Sanaa, prompting the Saudi-led intervention. The war has resulted in a severe humanitarian crisis, with millions displaced and facing starvation. The STC's presence adds another layer of complexity to the conflict, as it controls significant territory in the south and has repeatedly clashed with government forces over control of key infrastructure and resources. In December, the STC expanded its military operations in Hadramout, further exacerbating tensions.

The Saudi-led coalition has faced criticism for its airstrikes in Yemen, which have resulted in numerous civilian casualties. The United Nations has repeatedly called for a ceasefire and a negotiated settlement to the conflict. The suspension of flights from Aden airport will likely further complicate humanitarian efforts and restrict the movement of people and goods in and out of the city.

As of Thursday, the duration of the flight suspension remained uncertain. Reuters reported that airport officials were unable to provide a timeline for the resumption of services. The situation is being closely monitored by international organizations and diplomatic missions in the region.
