On August 7 1998, Lilian Munyiva reported on duty as usual. She worked on the 12th floor at Co-operative House. 

Munyiva was heavily pregnant and since it was a Friday, she looked forward to a restful weekend.

A month earlier, their offices had been moved from another location. Munyiva recalls how her boss, a Mr. Kangeta, decided to move her from sitting near the window to a corner. The move saved her life and that of her unborn child that fateful day on August 7 1998 when a truck bomb exploded outside the US Embassy in Nairobi.
“I wondered why he moved me. But I chose to obey. Where he asked me to sit, there was a pillar behind me and that is the pillar that saved my life, because the glasses did not reach me,” she says.

On the material day as Munyiva went about her business, around 10.30am, she heard a blast. The sheer force of the blast pushed her to the floor; sending shards of glass flying all over.
The air was filled with distressing cries and agonising screams - people calling mama and their maker. At first she thought she was dead, but dead people do not move and hear voices, right?
