The US drastically increased its attacks against ISIS last month, while Kurdish fighters made strong incursions into jihadist-controlled territories.
From July 15 to July 31, the US military averaged spending $4.6 million per day on bombs and other weapons. By comparison, it spent an average of $2.33 million per day in June.
According to a defense official, the second half of July nearly set a record since the attacks began last year, only falling behind the two weeks in September when the US first began acting in Syria.
