An explosion hit a Syrian military truck escorting a four-vehicle convoy of United Nations observers near the city of Deraa Wednesday (May 9th), the BBC reported.

The explosion hit seconds after a convoy carrying the head of the UN monitoring mission in Syria, Maj. Gen. Robert Mood, passed by.

Neither Mood, his spokesperson Neeraj Singh nor any of the 11 monitors with him were hurt, but at least six Syrian soldiers were wounded and the windows of the truck were shattered, AFP reported.

Mood said the attack was "a graphic example of violence that the Syrian people" were suffering from on a daily basis.

"It is imperative that violence in all its forms must stop," Mood said, according to Singh.

At least eight people were killed on Wednesday in violence across the country.

In Idlib province, near the town of Jisr al-Shughour, one civilian was killed and three were wounded by machine gun fire from government troops, and snipers killed an elderly man who was ploughing his field.

Clashes between government forces and armed opposition groups in Idlib's Marata village killed one solider, the Syrian Observatory for Human Rights reported.

Shots were also heard early Wednesday in several districts of Homs where two civilians were killed.

Two security forces members were killed in Deir ez-Zor, the scene of heavy shooting and explosions, and a pro-government gunman was killed in Aleppo.

In the village of Manshiya, near Deraa, several soldiers were killed and wounded when an explosion targeted their vehicle.
