In spite of the alleged “end of combat operations” June has seen both the deadliest day and the deadliest month in Iraq in over 2 years:

“Two American soldiers were killed Sunday in Iraq, the military command said, making June the worst month in combat-related fatalities for United States forces in Iraq in more than two years. The casualties also reflected the dangers ahead as the United States prepares to withdraw all its troops from Iraq by the end of the year.

[…]

In a statement issued Sunday night, the American military said the two soldiers were killed “conducting operations” in the north. It did not elaborate, but that terminology is usually meant to indicate the deaths were caused by enemy attack. In the deadliest single-day death toll since 2009, five soldiers were killed June 5 when a rocket struck Victory Base Complex, the military’s base near the Baghdad airport. A sixth later died of his wounds.”

I guess it all depends on what the definition of “combat operations” is.
