The Wall Street Journal reports that the Iranians are helping the Syrians with their crackdown:
Iran is secretly helping Syrian President Bashar al-Assad put down pro-democracy demonstrations, according to U.S. officials, who say Tehran is providing gear to suppress crowds and assistance blocking and monitoring protesters' use of the Internet, cellphones and text-messaging.
At the same time, communications intercepted by U.S. spy agencies show Tehran is actively exploring ways to aid some Shiite hardliners in Bahrain and Yemen and destabilize longstanding U.S. allies there, say U.S. officials familiar with the intelligence. Such moves could challenge interests of the U.S. and Saudi Arabia and inflame sectarian tensions across the Middle East, they say.
"We believe that Iran is materially assisting the Syrian government in its efforts to suppress their own people," said an Obama administration official.
