Iraqi forces continue to fight against independent militias inside Iraq. Funny, but the article does not mention Iran even once.
This is necessary and something I've wanted Iraq to do and complete for a long time:
Tensions mounted in Iraq's capital on Wednesday after the arrest of a militia commander on terrorism charges, prompting a dangerous showdown by the detainee's paramilitary supporters and the Iraqi government.
The confrontation began after Iraqi security forces arrested at dawn militia leader Qassim Mahmoud Musleh based on a judicial investigation and arrest warrant on terrorism charges, Iraq's military said in a statement. The statement said he was being questioned by a joint investigative committee.
This article is a copy of the above but adds the essential information in the headline, "Arrest of pro-Iran militia commander stirs up tensions in Iraq". Which seems important.
The tensions arise from Iran being unhappy with actions that most Iraqis support. And Iran is happy to have Arab allies die for Iran.
America and other coalition allies have a role in winning this Phase IX of the Iraq War, which is in large part a war against Iran inside Iraq.
