The head of a Muslim extremist group says he's happy to see the horror in America after the bombings in Boston.
Mohammad al-Chalabi is part of the Jordanian Muslim Salafi group.
In 2003, al-Chalabi was convicted in an al Qaeda-linked plot to attack the United States and other Western diplomatic missions in Jordan.
He said, "Let the Americans feel the pain we endured by their armies occupying Iraq and Afghanistan and killing our people there."
Meanwhile, security has been beefed up around the U.S. Embassy in Amman.
A counter-terrorism expert based in Jordan said the blasts "carry the hallmark" of terrorists groups like al Qaeda but didn't elaborate.
