The conflict in Syria intensified on Monday with scores of airstrikes that anti-regime activists called the most widespread bombing in a single day since Syria's troubles started 19 months ago, The Associated Press reports.
On Tuesday, Syrian warplanes bombed rebel positions on the outskirts of the central city of Homs to try to break a siege of an army base housing dozens of soldiers, opposition activists said.
