Explosive devices, believed by police to have potentially been grenades, killed six passengers and injured 69 others, according to The Guardian.
The attack, which occurred Saturday night, was reported by police to have involved three explosive devices that were thrown at a group of people waiting at a bus stop in Nairobi, thrown from a passing moving vehicle.
George Saitoti, the internal security minister of Kenya (whose status was not mentioned in the Boston.com article on the incident) stated that investigative authorities covering the attack believe those behind on the attack are sympathizers with Somalia's al-Qaida-linked al-Shabab militia.
"The group has been linked to a string of attacks on Kenyan soil since Kenya sent troops into Somalia in October," The Guardian wrote.
A difference between the two articles is the number of injured people. The Guardian wrote that 69 people were injured, and Boston.com reported that Saitoti stated that 63 were injured.
