Under the first of these, ToR A, new information on cetacean and seal population abundance, distribution, population/stock structure, was reviewed, including information on vagrant ma-rine mammal species. This was done to ensure the recording of possible range changes in marine mammal species in the future. For cetaceans, an update is given for the different species, providing for a latest estimate for all species studies. In this report, particular attention is given to the updating of information from Canadian and US waters, and together with those countries, latest estimates for cetacean species are provided. For seals, latest monitoring results are given for harbour, grey and Baltic ringed seals. In addition, where possible, local long-term trends are illustrated for those species, based on earlier WGMME efforts to assemble these data into the WGMME seal database. For both spe-cies’ groups, a first account of vagrant species is providedN

TWEED Code Book

The data set Terrorism in Western Europe: Events Data, TWEED, contains information on events related to internal (or domestic) terrorism in 18 West European countries (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom of Great Britain and Northern Ireland). By limiting itself to internal terrorism, the TWEED data set only includes events initiated by agents originating in the West European countries. In the TWEED data set, data has been collected for the period from 1950 to 2004. In total, 11.026 events are recorded in the TWEED data set. Of these, 9542 events (86.5%) are actions initiated by terrorist groups or non-state agents. The remaining events are government actions directed mainly against terrorists. The total number of deaths resulting from actions by terrorist agents recorded in the TWEED data set is 2959. The data set records activities by around 200 terrorist groups identified by name. The code book documents the structure of the data set and the variables included in it
