AlQa'dah 19, 1432, Oct 17, 2011, SPA - About 3,000 U.S. and Filipino marines started two weeks of annual military drills in the Philippines on Monday. U.S. Marine 1st Lt.

The exercises would ensure that U.S. and Philippine forces could jointly respond to "anything that arises," Eisenbeiser told The Associated Press.
