Over the months, we have been following the events in Syria with growing concern. We support the aspirations of the Syrian people to freely choose a government that represents all the enriching diversity of this multi-confessional nation, one that respects the rule of law, human rights and democracy. It is deplorable that the current regime in Damascus has not heeded the repeated calls for a peaceful transition of power. As do our colleagues from the Arab League, we strongly condemn the violence by the al-Assad regime against the Syrian people. We call on all sides to end the violence and to genuinely support the U.N.-led efforts to achieve a political solution.But recent developments have given reason for even more serious concern. U.N. peacekeepers were seriously injured when a convoy of the UNDOF peacekeeping operation on the Golan Heights was attacked. Reports about possible preparations for the use of chemical weapons circulate. The al-Assad regime is preparing Damascus for confrontation with the rebels and we know that these situations of last stand urban fighting often result in the most terrible atrocities being committed in armed conflict, with particular dangers for civilians. Concerned that the crisis in Syria may soon reach a new level of violence, we publicly appeal to all parties to the conflict to abide by international law, especially international humanitarian law and human rights law, and to recall that all those that commit or order war crimes and crimes against humanity will be held accountable. This principle cannot and will not be negotiated.
