Uber has officially halted its operations in Nigeria and Uganda, effective immediately. The decision follows a thorough internal review of the company's performance in the region. The ride-hailing giant cited the need to reassess its strategic direction and operational efficiency. Nigeria, Africa's most populous nation, had been a key market for Uber's expansion in the continent. The move marks a significant shift for the company as it continues to adjust its global footprint. The closure affects both drivers and passengers reliant on Uber's services in the two countries. The company has not provided further details on future plans for the region. The decision reflects broader trends in the tech sector, where companies are increasingly reevaluating their presence in emerging markets.
