There are news of at least 12 American soldiers have been killed and wounded near the Al-Bo-Kamal area when they followed insurgents escaped to Syria. Fighting then broke down with the Syrians who had at least 3 casualties.
A buffer zone as deep as 30-50 km is needed inside the Syrian border along the Iraqi borders to allow the Iraqi-American forces to penetrate to kill or arrest the insurgent terrorists. Syria has no choice but either to end fully its support for terrorists, that is not going to happen at all or to allow such buffer otherwise it will face serious consequences.
A UN resolution regarding the support of terrorists by the Syrian may now become essential due to their failure to end that support, however for the multinational and Iraqi troops they need the zone to protect themselves and the civilians.
