President Barack Obama Tuesday warned against a rush to judgment on Syria's use of chemical arms, but said proof of their use would trigger a "rethink" of his reluctance to use military force. As critics complain that he let Syria cross a US "red line," Obama said Washington believed chemical weapons had been used in the country's vicious civil war but did not know exactly who had fired them.

President Barack Obama on Saturday called on the US Congress to end the "reckless" and "dumb" budget cuts known as the sequester, and to adopt a plan of "smarter" cuts to fuel economic growth. Obama's weekly address comes after Congress on Friday overwhelming approved a bill putting furloughed air traffic controllers back on the job, thus undoing one of the most high-profile effects of the so-called sequestration, the $85 billion in automatic budget cuts that took effect March 1 and hit federal spending across the board.

Boston, Apr 18 (EFE).- U.S. President Barack Obama said Thursday that those responsible for the bombings at the Boston Marathon will be found and will be brought to justice in his speech at an interfaith service at this city's Cathedral of the Holy Cross. After citing the words of a poet who once described Boston as "the perfect state of grace," Obama said: "we also come together today to reclaim that state of grace - to reaffirm that the spirit of this city is undaunted, and the spirit of this country shall remain undimmed."

US President Barack Obama vowed Thursday that the Boston marathon bombers would be found and held "accountable" as investigators focused their efforts on two potential suspects. "Yes, we will find you, and yes, you will face justice," Obama told a special service in the city, three days after the two bombs killed three people and injured about 180 in a hail of nails and ball bearings. "We will find you, we will hold you accountable," he added in a keynote speech on a special visit to show national solidarity with what he called "one of the world's great cities."
