A combination of two file pictures made on August 31, 2013 shows US President Barack Obama (L) speaking to journalists on April 30, 2013 in Washington and Syrian President Bashar al-Assad speaking to journalists on December 9, 2010 in Paris.
President Barack Obama says he has decided that the United States should take military action against Syria in response to a deadly chemical weapons attack.
But he says he will seek congressional authorization for the use of force.
He says congressional leadership plans to hold a debate and a vote as soon as Congress comes back in September.
Obama says he has the authority to act on his own, but believes it is important for the country to have a debate.
Military action would be in response to a chemical weapons attack the U.S. says Syrian President Bashar Assad's government carried out against civilians. The U.S. says more than 1,400 Syrians were killed in that attack last week.
