BEIRUT -- U.N. monitors on Friday got their first direct look at a farming village where nearly 80 men, women and children were reportedly killed earlier this week in the latest massacre in Syria, saying they found body parts and damaged homes.
Also Friday, explosions echoed over Damascus as Syrian troops clashed with rebels in some of the heaviest fighting yet in the capital in the 15-month uprising against President Bashar Assad. Troops also unleashed a heavy assault to retake a rebel-held neighborhood in a central flashpoint city, blasting it with heavy bombardment.
The U.N. monitors were able to enter the remote farming area of Mazraat al-Qubair on Friday, a day after being blocked by troops and local residents and came under gunfire.
"You can smell the burnt smell of the dead bodies," said Sausan Ghosheh, spokeswoman of the U.N. observers. "You could also see body parts in and around the village."
It was the most independent observation yet of a mass killing that was earlier reported by activists and Syrian government officials, who exchanged blame over who exactly, hacked, stabbed, and burnt to death up to 78 men, women and children, in the rural village of Mazraat al-Qubair in the central Homs district on Wednesday.
But Ghosheh said that residents' testimonies of the mass killing was "conflicting," and that they needed to cross check the names of the missing and dead with the those supplied by nearby villagers. She said the village of Mazraat al-Qubair itself was "empty of the local inhabitants."
Ghosheh said the scenes that immediately struck her eye were two homes damaged by shells and bullets. One home had burnt bodies inside, she said.
The fighting in Damascus erupted in the restive district of Kfar Souseh, where the night before, armed rebels took part in a large anti-government rally in the same district, witnesses said -- a rare and bold public appearance by the fighters in the capital.
Friday's fighting began when the fighters attacked a government checkpoint in the morning, according to Rami Abdul-Rahman, of the Britain-based Syrian Observatory for Human Rights. A witness who spoke on condition of anonymity for security concerns said explosions could be heard throughout central Damascus and that smoke could be seen rising from the area. Amateur video uploaded by activists in Damascus showed plumes of smoke, explosions that rocked buildings and sporadic gunfire that thickened into steady bursts of bullet fire.
The Observatory and another activist group, the Local Coordination Committees, said clashes also broke out in three nearby districts in the capital. There was no immediate word on civilian casualties but the LCC said three rebels were killed.
The Syrian government news agency said armed groups also partially damaged a power generator in the capital Damascus, causing blackouts through the capital.
In the central city of Homs, one of the main battlegrounds of the uprising, regime troops were trying to advance into the opposition-held district of Khaldiyeh from three sides, battling with armed rebels trying to stop them, said Tarek Badrakhan, an activist based in the neighborhood speaking via Skype.
"This is the worst shelling we've had since the start of the revolution," he said. A shell could be heard exploding in the background as he spoke.
Shells were hitting the neighborhood at a rate of five to 10 a minute, said the Britain-based Syrian Observatory for Human Rights. "It seems they are trying to enter it today," it said.
The Observatory and another activist group, the Local Coordination Committees, had no immediate word on casualties. Amateur videos posted online showed a small white plane, apparently a drone, flying over Homs.
Amateur videos showed missiles exploding into balls of flames in the crowded concrete jumble of homes, with thundering crashes that sent plumes of heavy gray smoke over Homs. The videos suggested the attack began at dawn, as birds chirped, roosters crowed, and the sun cast a yellow glow. In one video, the missiles came in rapid succession, four exploding in less than a minute.
Homs has been one of the hardest hit regions in Syria since the start of the uprising. In April, the U.N. said more than 9,000 people have been killed since the crisis began, but it has been unable to update its estimate since and the daily bloodshed has continued in past weeks. Activists put the number of dead at about 13,000.
The reported killings in Mazraat al-Qubair would be the fourth such mass killing of civilians in Syria in the last two weeks. The deadliest took place last month in a string of villages known as Houla, where 100 people were killed. The opposition and the regime blamed each other for the Houla massacre.
The government denied responsibility for the Mazraat al-Qubair deaths as well. It said a "terrorist group" killed nine women and children in the hamlet. It said residents appealed for protection from Hama authorities, who sent security forces who went to the farm, stormed a hideout of the group and clashed with its fighters.
In Geneva, International Committee of the Red Cross spokesman Hicham Hassan told reporters Friday that the humanitarian situation in Syria was worsening.
"Currently the situation is extremely tense, not only in Houla, not only in Hama, but in many, many places around the country," he said. He noted the countryside around the northern city of Idlib, suburbs of the capital Damascus, the eastern province of Deir el-Zour and the coastal region of Latakia had all seen attacks.
On Friday, troops fired tear gas and live ammunition in several locations across the country in an attempt to disperse thousands of anti-government protesters, activists said, including the northern provinces of Idlib and Aleppo, the southern region of Daraa and the suburbs of the capital, Damascus. There was no immediate word on casualties.
Syria's state-run media said armed "terrorist groups" attacked military units charged with protecting al-Omar oil field of al-Furat Oil Company in the oil-rich city of Deir Ezzor province. The official news agency SANA said several gunmen were killed in the Friday attack.
SANA also said a car bomb in the Damascus suburb of Qudsaya killed three policemen, while another explosion in the northern city of Idlib killed two soldiers and three civilians.
In Brussels, Kristalina Georgieva, European commissioner for humanitarian aid, said there are 1 million "vulnerable people who need humanitarian assistance" in Syria.
"Between 200,000 and 400,000 are internally displaced ... and we have 95,000 refugees in Turkey, Lebanon and Jordan primarily," she said.
U.N. patrols in Syria have on several instances been deliberately targeted with heavy weapons, armor-piercing ammunition and a surveillance drone, U.N. Secretary-General Ban Ki-moon told the Security Council on Thursday, according to a senior U.N. official. The official, speaking on condition of anonymity because the council meeting was closed, said Ban also reported repeated incidents of firing close to U.N. patrols, apparently to get them to withdraw.
International envoy Kofi Annan, whose peace plan brokered in April has not been implemented, warned against allowing "mass killings to become part of everyday reality in Syria."
"If things do not change, the future is likely to be one of brutal repression, massacres, sectarian violence, and even all-out civil war," Annan told the U.N. General Assembly in New York. "All Syrians will lose."
U.N. diplomats said Annan was proposing that world powers and key regional players, including Iran, come up with a new strategy to end the 15-month conflict.
