Syria 
The Syrian Government in 2004 continued to provide political and material support to both Lebanese Hizballah and Palestinian terrorist groups. HAMAS, Palestinian Islamic Jihad (PIJ), the Popular Front for the Liberation of Palestine (PFLP) and the Popular Front for the Liberation of Palestine-General Command (PFLP-GC), among others, continue to operate from Syria, although they have lowered their public profiles since May 2003, when Damascus announced that the groups had voluntarily closed their offices. Many of these Palestinian groups, in statements originating from both inside and outside of Syria, claimed responsibility for anti-Israeli terrorist attacks in 2004. The Syrian Government insists that these Damascus-based offices undertake only political and informational activities. Syria also continued to permit Iran to use Damascus as a transshipment point for resupplying Lebanese Hizballah in Lebanon. 
Syrian officials have publicly condemned international terrorism, but make a distinction between terrorism and what they consider to be the legitimate armed resistance of Palestinians in the occupied territories and of Lebanese Hizballah. The Syrian Government has not been implicated directly in an act of terrorism since 1986, although Israeli officials accused Syria of being indirectly involved in the August 31, 2004, Beersheva bus bombings that left 16 dead.

Damascus has cooperated with the United States and other foreign governments against al-Qa’ida and other terrorist organizations and individuals; it also has discouraged signs of public support for al-Qa’ida, including in the media and at mosques. 
In September 2004, Syria hosted border security discussions with the Iraqis and took a number of measures to improve the physical security of the border and establish security cooperation mechanisms. Although these and other efforts by the Syrian Government have been partly successful, more must be done in order to prevent the use of Syrian territory by those individuals and groups supporting the insurgency in Iraq.
