GENEVA, June 27 (Reuters) - Syrian government forces have committed human rights violations, including executions, across the country "on an alarming scale" during military operations in the past three months, United Nations investigators said on Wednesday.
Their report, presented by investigation head Paulo Pinheiro to the United Nations Human Rights Council in Geneva, also listed multiple killings and kidnappings by armed opposition groups trying to topple President Bashar al-Assad.
"The situation on the ground is dangerously and quickly deteriorating," the 20-page report said.
"In the increasingly militarised context, human rights violations are occuring across the country on an alarming scale during military operations against locations believed to be hosting defectors and/or those perceived as affiliated with anti-government armed groups, including the Free Syrian Army," it said.
Syria's ambassador dismissed the accusations and threatened to end cooperation with international agencies.
The investigation's report also said it was unable to determine who carried out a massacre of more than 100 people in Houla in May but that forces loyal to Assad may have carried out many of the killings.
Government troops were using machine guns, artillery and tanks to assault restive areas, including the city of Homs. For their part the rebel forces were increasingly using improvised explosive devices, it said.
The U.N. investigators voiced concern that rebels were using children as medical porters, messengers and cooks, exposing them to risk of death and injury. Some had been going back and forth across the border with Turkey, they said, citing interviews with four who had been wounded by sniper fire.
Pinheiro, who made a first visit to Damascus at the weekend for talks with senior Syrian officials, presented the report to the U.N. Human Rights Council which set up the international inquiry last September.
The Brazilian expert had discussed the Houla investigation with Syrian authorities and believed that the team would be able to begin working inside Syria, he told the 47-member forum.
Syria's ambassador Faysal Khabbaz Hamoui took the floor in the debate to dismiss the accusations as being based on testimony from people fleeing justice and "tendentious media".
"All sides recognise now that the crisis is not attributable to peaceful demonstrations and legitimate demands for reform. The crisis in Syria is a genuine war," Khabbaz Hamoui said.
Denouncing the meeting as politicised, he said: "This all induces us to seriously consider ceasing all forms of cooperation with agencies concerned as long as they are powerless to provide a constructive solution to the problems."
Russian diplomat Vassily Nebenzia, whose country is Assad's main defender, said that Syrian militants were carrying out daily attacks on state institutions and infrastructure and killing civilians.
"A war of minds and bombs is taking place. Gunmen have been carrying out terrorist acts on Syrian cities. Such activities by gunmen and terrorists is being fed with money and weapons from abroad," he said.
Western powers called for Pinheiro's commission to be given "full and unfettered accesss" to Syria immediately.
"The evidence is introvertible. The Assad regime is waging a brutal campaign against the Syrian people, characterised by aerial bombardment, mass killings, rape and other atrocities," U.S. ambassador Eileen Chamberlain Donahoe said in her speech.
The U.N. team, which conducted nearly 400 interviews, said it had collected photographs, videos, satellite imagery and other documentary evidence during its recent investigative missions in the region.
It was updating its list of identified perpetrators for possible use in future criminal prosecutions for war crimes and crimes against humanity.
"The commission's work is indispensable in view of ensuring that those responsible for widespread, systematic and gross human rights violations be held to account," the European Union's ambassador Mariangela Zappia said. (Reporting by Stephanie Nebehay; Editing by Angus MacSwan)

How Do Syrian Fighters Get Their Arms?
How do Syria's fighters get their arms? An overview put together by Reuters explains that there are three gateways to the country -- Lebanon, Turkey, and Iraq.
Syrian rebels are smuggling small arms into Syria through a network of land and sea routes involving cargo ships and trucks moving through Turkey, Lebanon and Iraq, maritime intelligence and Free Syrian Army (FSA) officers say.
Western and regional powers deny any suggestion they are involved in gun running. Their interest in the sensitive border region lies rather in screening to ensure powerful weapons such as surface to air missiles do not find their way to Islamist or other militants.

Hama Revolutionary Council: More Than 220 Killed
According to the Hama Revolutionary Council, a Syrian opposition group, more than 220 people have been killed in a new alleged massacre in Taramseh. Earlier reports said more than 100 people were killed. "More than 220 people fell today in Taramseh," the Council said in a statement. "They died from bombardment by tanks and helicopters, artillery shelling and summary executions."
Fadi Sameh, an opposition activist from Taramseh, told Reuters he had left the town before the reported massacre but was in touch with residents. "It appears that Alawite militiamen from surrounding villages descended on Taramseh after its rebel defenders pulled out, and started killing the people. Whole houses have been destroyed and burned from the shelling," Sameh claimed.
