On the 15th of June 2023 in Madrid, thirty-four participants from health, security and civil protection sectors from 12 countries attended a tabletop exercise organised by the Spanish Ministry of Health, within the framework of Joint Action TERROR (WP6). Participants were guided to solve a two-part scenario in limited time: 1) a VX-release in the public transport at national level and 2) a mass gathering terror attack with VX at international level.

Sector-specific responses to the different injects were collected as well as gaps, good practices and proposed actions identified, with a focus on cross-sectoral collaboration. Specific preparedness and response actions were assessed by designated evaluators through a checklist.
