No of attackers at Kenya mall may have been fewer

A top Kenya government official says four armed assailants can be seen on closed circuit television footage during the terrorist attack on an upscale mall in which at least 67 people were killed, an indication that there may not have been as many attackers as initially believed.
Kenya's government had initially said 10-15 attackers were at the Westgate Mall. Al-Qaida-linked Somali militant group al-Shabab claimed responsibility for the deadly attack there.
The government official spoke on condition of anonymity today because he is not supposed to comment on an ongoing investigation.
Al-Shabab has threatened more terrorist attacks on Kenya for sending its troops to Somalia.
