WASHINGTON -- U.S. fighters dropped bombs on Islamic militants in Iraq Friday, the Pentagon said, carrying out President Obama's promise of military force to counter the advancing militants and confront the threat they pose to Iraqi civilians and Americans still stationed there.
Pentagon press secretary Rear Adm. John Kirby said that two F/A-18 jets dropped 500-pound bombs on a piece of artillery and the truck towing it. Kirby said the fighters had taken off from the aircraft carrier USS George HW Bush in the Persian Gulf to conduct the mission. He said it wasn't clear how many militants might have been killed in the strike.
The Pentagon said the militants were using the artillery to shell Kurdish forces defending Irbil.
For the United States, it was a re-engagement in the long sectarian war from which American combat forces had been withdrawn -- on Obama's orders -- in late 2011.In a televised speech Thursday night, Obama threatened to renew U.S. military involvement. At the same time, he announced that U.S. military planes already had carried out airdrops of food and water, at the request of the Iraqi government, to tens of thousands of Iraqi religious minorities atop a mountain surrounded by militants and desperately in need of supplies. "America is coming to help," Obama declared. Speaking to reporters while traveling in India Friday, Defense Secretary Chuck Hagel said the U.S. military has sufficient intelligence resources and assets in place to launch strikes by both manned and unmanned aircraft in the region. Asked if the Islamic State group could successfully hide among civilians to evade strikes, Hagel said if the Islamic State moves against Irbil, Baghdad or the refugees trapped on a mountain, "it's pretty clear who they are, and they would be pretty identifiable where our airstrikes could be effective." The Yazidis, who follow an ancient religion with ties to Zoroastrianism, fled their homes after the Islamic State group issued an ultimatum to convert to Islam, pay a religious fine, flee their homes or face death. "Earlier this week, one Iraqi in the area cried to the world, 'There is no one coming to help.' Well, today, America is coming to help," Obama said. "We're also consulting with other countries -- and the United Nations -- who have called for action to address this humanitarian crisis." The announcement reflected the deepest American engagement in Iraq since U.S. troops left. Obama, who made his remarks in a steady and somber tone, has staked much of his legacy as president on ending what he once called the "dumb war" in Iraq. Mindful of the public's aversion to another lengthy war, Obama acknowledged that the prospect of a new round of U.S. military action would be a cause for concern among many Americans. He vowed anew not to put American combat troops back on the ground in Iraq and said there was no U.S. military solution to the crisis. "As commander in chief, I will not allow the United States to be dragged into fighting another war in Iraq," Obama said. Even so, he outlined a rationale for airstrikes in the event the Islamic State militants advanced on American troops in Irbil and the U.S. consulate there in the Kurdish region of Iraq. The troops were sent to Iraq earlier this year as part of the White House response to the extremist group's swift movement across the border with Syria and into Iraq.
