 Such groups have been allegedly responsible for violent attacks and suicide bombings at Shi'a gatherings at mosques and shrines, most notably in Iraq during the Ashura mourning ceremonies where hundreds of Shias were killed in coordinated suicide bombings, but also in Pakistan and Afghanistan.However, in a video message, Al-Qaeda deputy Dr Ayman al-Zawahiri directed Abu Musab al-Zarqawi, of Al-Qaeda in Iraq, not to attack civilian targets but to focus on the occupation troops.His call seems to have been ignored, or swept away in the increasing tensions of Iraq under occupation.
