Eleven people died and 45 were wounded in the al-Qaeda attack that happened 25 years ago today. In a near-simultaneous bombing of the US embassy in Nairobi, the capital of neighbouring Kenya, more than 200 people died.

Ms Buberwa was working at the embassy in Dar es Salaam at the time.

"The deaths of my co-workers are something I will never forget," she told BBC Swahili.

"I was with them that morning; I spoke with them, then went out for assignment with my boss; when I returned to the office, they were gone.

"There were several victims, many of whom were bleeding, and there was widespread fear.

"It took a long time for me to get over the recollections. When I recall, pictures come to me, such as the truck driver at the gate being hit by metal, and when I came to the gate, I saw that his leg was broken.

"There was a security guard manning the gate. When we departed for our mission with my boss, I bid goodbye to her, but when we returned after the explosion, I found her dead on the ground.

"There was another security guard who eventually recovered and was laying on top of the girl, weeping uncontrollably."
