A witness testifying in Kenya in the trial of a former diplomat charged with the murder of the acting Venezuelan ambassador says the embassy's diplomatic bag was used to traffic drugs.

Prosecution witness Kevin Lameck, who worked as a driver at the embassy in Nairobi, was answering questions Wednesday from the defense lawyer in the trial of former Venezuelan first secretary Dwight Sagaray.

Sagaray is accused of murdering acting Ambassador Olga Fonseca.

Lameck said the drugs came in during the tenure of Fonseca's predecessor and Sagaray was never allowed to touch the bag.

Fonseca was found strangled in the embassy's official residence on July 27, 2012. She had reported to Kenya only 12 days earlier.
