In the statement, published on radical Islamist Web sites, the group hailed the "brother" who carried out the "heroic attack." The group said it tested a "new kind of explosives" in the attack, and hailed the fact that the explosives "passed through security."
The group threatened further attacks, saying, "since Americans support their leaders they should expect more from us."
"We have prepared men who love to die," the statement dated Saturday said.
