Uncertainty lingers after Garissa attack

A month after the bloody attack on Garissa University by Al-Shabaab terrorists, questions remain over the lessons learnt from this and other grisly terror attacks on Kenyan soil.

The April 2 incident left 148 people dead, the second highest fatality figures from a single terror attack in this country, the highest being the 1998 Al-Qaeda bombing of the United States embassy that left 218 dead.
