In Afghanistan, U.S. troops have started their withdrawal as part of the U.S.-Taliban agreement, as political turmoil deepens following dual inaugurations Monday. Afghan President Ashraf Ghani and rival leader Abdullah Abdullah both held inaugural ceremonies — interrupted briefly after explosions were heard, though no injuries have been reported. The fate of intra-Afghan talks, due to kick off today, remains uncertain. The U.S. is calling for the U.N. Security Council to endorse its deal with the Taliban.
