The U.S.-led coalition withdrew on Sunday from a military base in northern Iraq that nearly launched Washington into an open war with neighboring Iran. The K1 Air Base is the third site coalition forces have left this month in line with U.S. plans to consolidate its troops in two locations in Iraq. The attacks culminated in the U.S.-directed killing of top Iranian general Qassim Soleimani and senior Iraqi militia leader Abu Mahdi al-Muhandis.
