Washington, September 24 (RHC)-- The U.S.-led bombing of militant targets inside Syria has intensified as Pentagon officials acknowledge a military mission that could take years. On Tuesday, American and other coalition forces launched more than 200 strikes on Islamic State targets.

Speaking from the White House, President Obama vowed to "take the fight" to ISIS. Later in the day, President Obama met with leaders of the Arab countries reportedly taking part in the strikes — Bahrain, Jordan, Saudi Arabia, the United Arab Emirates and Qatar — on the sidelines of a one-day U.N. climate summit in New York City.

Despite talk of an international coalition, The New York Times reports the United States is carrying out the vast majority of airstrikes from its warplanes and naval carriers.
