Following the terrorist attacks of unprecedented violence committed in the United States of America on 11 September 2001, the Council of Europe decided in November 2001 “to take steps rapidly to increase the effectiveness of the existing international instruments within the Council of Europe on the fight against terrorism by, inter alia, setting up a Multidisciplinary Group on international action against Terrorism (GMT)”.
The GMT had the task of revising the 1977 European Convention on the Suppression of Terrorism (ETS No. 90) and identifying the priorities for future action by the Council of Europe (more).
It had 6 meetings from 2001-2002 and completed its mandate by preparing an Amending Protocol to the 1977 European Convention on the Suppression of Terrorism (ETS No. 190) and submitting to the 110th Session of the Committee of Ministers (Vilnius, 3 May 2002) a Progress Report on the action which the Council of Europe could usefully carry out in the field of the fight against terrorism. It was replaced in 2003 by the Committee of Experts on Terrorism (CODEXTER).
