Missile strikes against Syria could be launched “as early as Thursday,” senior U.S. officials said Tuesday as the White House intensified its push toward an international response to the suspected use of chemical weapons.

The “three days” of strikes would be limited in scope, and aimed at sending a message to Syria's President Bashar Assad rather than degrading his military capabilities, U.S. officials told NBC News.

News on the possible timescale for military action followed another round of telephone diplomacy by President Barack Obama and his administration.

Obama held discussions with Australian Prime Minister Kevin Rudd and French President Francois Hollande on Monday, while Secretary of State John Kerry spoke to U.N. Secretary General Ban Ki-moon in addition to political leaders in Britain, France, Jordan Turkey, Saudi Arabia, United Arab Emirates and Qatar.

Secretary of State John Kerry says the use of chemical weapons in Syria is "undeniable" and that the U.S. is considering how to respond. Watch his entire statement

British Prime Minister David Cameron recalled his country's Parliament from vacation on Tuesday and said lawmakers would vote Thursday on a proposal for action.

Defense Secretary Chuck Hagel told the BBC that the U.S. military was" ready to go" with any action ordered by the White House.
