Grenade Attack After Kenyan Warning

One day after the U.S Embassy in Kenya warned of a possible terror attack and told citizens to delay traveling in that country, a grenade attack at a Nairobi nightspot injured twelve. No one has taken claim for the attack, but there are suspicions it may have come at the hands of Al-Shabaab in retaliation for Kenyan troops crossing the border with Somalia in pursuit of the militants.
