(FOX NEWS) The Obama administration on Tuesday was set to build the public case for a military strike on Syria by releasing documents on last week's alleged chemical weapons attack -- with one senior Defense official telling Fox News that a U.S. strike is "not a matter of if, but when."
One day after Secretary of State John Kerry declared that the evidence of a chemical weapons attack last week in Syria in "undeniable," the White House was expected to release intelligence backing up that claim. A source close to the White House told Fox News that the documents will probably be released on Tuesday.
Kerry and others have said the U.S. and its allies must respond, if for no other reason than to deter governments around the world from using chemical weapons in the future. Opposition and human rights groups in Syria have said the attack last week killed hundreds, though estimates of the death toll fluctuate widely.
