Al Qaeda target: Obama's grandmother?

The Somali terror group Al Shabaab has issued a personal threat against Sarah Obama, President Obama's step-grandmother, who lives in Kenya, ABC News reports.

Kenyan officials have provided Mrs. Obama with additional security Thursday, even though security had already been increased following the United States' assassination of Osama bin Laden.

But there is no new or credible threat to President Obama's grandmother, an expert involved in security matters at the U.S. embassy in Kenya told CBS News.

Local police added security around only out of abundance of caution.

Although, the embassy is under constant threat, they know of nothing new regarding Mrs. Obama.

Al Shabaab, a group loosely linked to al Qaeda, has long been a faction in the Somali civil war and has been linked to piracy, beheadings, and terror links to Somali communities in the United States.

Of course, the Al Shabab threat may amount to little more than posturing. Al Qaeda and its affiliates have issued numerous threats in the wake of bin Laden's killing, most of them broad threats of reprisal against the West and assertions of the groups' continuing relevancy.
