U.S. Attorney General questions al-Shahab's capacity to attack America

U.S. Attorney General Eric Holder has said the intelligence community has still not received any credible evidence on whether Al Qaeda-linked terror group, Al-Shahab, which claimed responsibility for Nairobi mall massacre, had the capacity to conduct a similar strike on American soil.

A senior law enforcement official said the terrorist group is focused on striking Western targets in Africa, like Kenya and Ethiopia, to drive the security forces out of Somalia, instead of striking the U.S. homeland, ABC News reports.

A recent joint intelligence statement issued by the FBI and the Department of Homeland Security also claimed that al Shabab is not planning any follow-on attacks in East Africa presently.

According to the report, the Nairobi mall massacre was designed to cause mass casualties to gain media coverage in order to spread a message of their dominance in Africa.
