Lead section says the cell was responsible for a decade of activity edit

I don't know of this is just my interpretation of the lead section, but it says the cell was "responsible for a decade of ..." terrorist activity. However, the timeline only lists about 4 months of activity in 1970. While I can understand the wider organization might have been responsible for this decade of activity, that is inconsistent with the timeline. Either there is more to add to the timeline or the lead is incorrect. This article needs to address questions like: When did the cell form? and What activities did the cell undertake?, and distinguish these activities from what the rest of the organization did. - Cameron Dewe (talk) 23:56, 1 October 2022 (UTC)Reply
