Al-Shabaab bombs UN Workers in Somalia

On April 20, 2015 nine people were killed when a van was blown up by the terrorist group al-Shabaab in Somalia.  The van was travelling from a guest house to a United Nations office.  It is interesting to me that, a vehicle carrying some very important passengers, someone didn't take better precautions to protect the passengers.  I wonder what would have happened had the bomb exploded once they reached their destination.
