At the time UN observers were continuing their visit to the Syrian cities on Sunday a rocket-propelled grenade exploded near a team of UN observers in a Damascus suburb.
  
No one was hurt in the Douma blast, which came as UN truce mission head Major General Robert Mood and peacekeeping chief Herve Ladsous were leading observers around the north Damascus suburb.

The device in Douma, a rocket propelled-grenade according to a Syrian army officer in the area, exploded just a few dozen meters (yards) from the UN team.
  
The UN observers could not immediately confirm the nature of the explosion, but urged all parties to respect the ceasefire that went into effect on April 12 and put an end to fighting.

Ladsous reported meeting Syrian Foreign Minister Walid Muallem earlier on Sunday to discuss the observers' mission. "There are still some aspects that need to be discussed regarding the function of the mission," said Ladsous, adding "there were still more aspects that needed to be looked at and worked out cooperatively."
  
State-run SANA news agency said Moallem informed Ladsous that armed rebels had violated the UN-backed ceasefire hundreds of times. "The armed opposition has carried out 3,500 violations since the ceasefire was established," Moallem's spokesman Jihad Makdisi was quoted as saying.

NATO chief Rasmussen said at a NATO summit, that the Chicago summit strongly condemned “the behavior of the Syrian security forces and their crackdowns on the Syrian population.” "But again NATO has no intention to intervene in Syria," he said as the United States was persistent on supplying communication equipment and night-vision goggles to Syrian rebels.
  
Rasmussen urged the Syrian regime to comply with a UN ceasefire and peace plan, saying it was "the best platform for finding a solution in Syria".
