GAZA CITY, Gaza Strip — The date of Aug. 15, 2009, marked a dramatic development in the relationship between Hamas and Salafist groups in the Gaza Strip. The relationship between the two was ruined that day when security forces loyal to Hamas attacked the Ibn Taymiyyah Mosque in Rafah in the southern Gaza Strip, which was controlled at the time by the Salafist-jihadist Jund Ansar Allah Party, led by Sheikh Abdel-Latif Moussa. The attack killed him and dozens of his supporters holed up in the mosque.
The relationship has been marked by constant tension ever since.
