Washington, November 8 (RHC)-- U.S. President Barack Obama has authorized the deployment of up to 1,500 more American troops to Iraq to fight the ISIL Takfiri militant group in the country. The Pentagon said on Friday that the soldiers expanded the U.S. mission of "training and advising Iraqi forces."

Pentagon spokesman Rear Adm. John Kirby announced that U.S. Defense Secretary Chuck Hagel recommended the extra troops, which will operate from bases outside Baghdad and Erbil. The Obama administration is set to ask Congress for another $5.6 billion to fund the fight against the terrorist group.

Meanwhile, the Pentagon said that the U.S.-led airstrikes targeting ISIL terrorists in Iraq and Syria cost the country more than $8.3 million per day. The Defense Department had previously put the average daily cost of the military offensive at $7.6 million a day.

A Pentagon official said the higher figure reflects the increased pace of airstrikes and related flights.
