The sharp rise in deaths from assaults in Nigeria last year was a tragic reminder of the importance of security measures for protecting staff and contractors. In 2006, our regional network of security advisers was expanded to provide practical and immediate support to our operations. In 2006, we experienced significant security incidents, such as armed robbery, kidnappings and vandalism, in 19 countries. Armed security was also used in 19 countries. This data is obtained from our internal questionnaire of the most senior Shell representative in each country. See the Performance Data page for more on this data.
