A Pentagon report suggests that the United States is carrying out roughly 85 percent of the airstrikes against Islamic State in Iraq and Syria.
According to a detailed report obtained by FOX News, US fighter planes and drones have conducted 819 strikes, compared to 157 from the 10 other countries.
US, along with Australia, France, Belgium, the Netherlands and the United Kingdom have been jointly conducting airstrikes on areas controlled by the Islamic State.
The five countries joined the US initiative after President Barack Obama called for other countries to participate in the international fight against the Islamic State.
The US ordered the strikes in Syria on Sept. 23, about 72 hours after five Arab nations-Bahrain, Jordan, Qatar, Saudi Arabia and United Arab Emirates-agreed to participate, the report added.
