TORONTO -- A Canadian woman kidnapped in Kenya says it was five minutes of shock as gunmen seized her and three other aid workers from a refugee camp.

After that, Qurat-Ul-Ain Sadazai, of Gatineau, Que., says they were driven off then marched by night some 70 kilometres into Somalia.

Speaking from Nairobi, Sadazai, 38, says she believes the kidnapping was motivated by money rather than ideology.

She also says the hostage-taking appears to have been well planned.

The four were rescued Monday after three days in Somalia, when Kenyan authorities swooped down on the group, killing one kidnapper.

Also kidnapped and rescued were Steven Dennis, 37, of Toronto, Astrid Sehl, 33, of Norway, and Glenn Costes, 40, a Filipino, who was shot and injured during the initial kidnapping.
