Nairobi, Kenya -

A witness wounded in a blast in downtown Nairobi says that the explosion occurred soon after a bearded man left a bag near her stall.

Irene Wachira spoke to The Associated Press from a Nairobi hospital bed on Monday. Wachira said the man came to the stall three times and acted as if he were interested in buying something. Wachira said the third time he came with a bag, he left it behind and then there was a blast.

Wachira described the man as “Arabic-looking” because of his relatively light skin. A doctor told AP that another person wounded in the blast said a Somali-looking man left behind the bag.

Police have not directly blamed terrorism, but Kenyan Prime Minister Raila Odinga called the explosion “a heinous act.” - Sapa-AP
