Iran's deadly missile strike in northern Iraq has heightened tensions in the region. The Iraqi government has condemned the attack, which killed civilians, and has taken diplomatic action against Iran. The strike comes amid existing conflict in the Middle East and has drawn criticism from the United States, France, and Britain. Iran claims the attack was in retaliation for previous incidents, but Iraq has rejected this explanation. The strike complicates negotiations for the withdrawal of U.S. troops from Iraq and has raised concerns about regional stability.
