Anna Murison, head of the global jihad analysis team with , a specialist intelligence company that forecasts commercially relevant political and violent risks worldwide, said her firm does not foresee the likelihood for retaliatory attacks in many regions. However, Yemen and Saudi Arabia are countries where businesses and foreign travelers might want to take extra precautions.

"Attacks are reasonably unlikely to come out of Pakistan because Al Qaeda leaders there are going to be looking at their own security measures and trying to figure out how the security leak happened and shutting down any plans that they had underway," said Murison. "But in Yemen, where Al Qaeda has been at the forefront of many terrorist operations, they are not under as much pressure. We know they have significant terrorist capabilities in these regions because they have demonstrated that in the past."

Murison said any potential terrorist activity would likely be done to make the statement that Al Qaeda is still relevant following Bin Laden's death.

"There's a point to prove there," said Murison.
