An attack at the Dusit D2 hotel on 14 Riverside Drive, Westlands Nairobi on Tuesday afternoon sparked tension countrywide as details developed.
What we know so far is that four perpetrators arrived at the junction linking Chiromo Lane with Riverside Drive and remained parked for thirty minutes before the incident.
They then forced their way into the parking lot and thereafter a huge explosion, believed to have been a suicide bomber, went off at 3:50 pm at the Secret Garden Hotel.
Some reports indicate that the four may have created an entry point for more cars to access the building.
