BEIRUT (Reuters) - Iran said pro-Damascus forces would press ahead with attacks on an insurgent enclave near the Syrian capital, as ground fighting raged on there in defiance of a U.N. resolution demanding a 30-day truce across the country.
Turkey, too, said its military operations in another theater of war in the north of Syria would not be affected by the unanimous Security Council vote demanding the truce to allow for aid access and medical evacuations.
Anti-government rebels said they clashed with pro-government forces near Damascus on Sunday, as rescuers and residents said warplanes struck some towns in the eastern Ghouta pocket.

The Syrian Observatory for Human Rights said air strikes and artillery killed nine people and injured 31 in the eastern suburbs. The UK-based monitoring group said Sunday's bombing was less intense than attacks over the past week.
There was no immediate comment from the Syrian military.
The latest escalation by Damascus and its allies has killed more than 500 people in the enclave over the last week, the Observatory says. The dead included more than 120 children.
Signaling the war remained a top focus of world leaders, the Kremlin said Russian President Vladimir Putin and French and German counterparts Emmanuel Macron and Angela Merkel spoke by phone and discussed the ceasefire's implementation.
Iranian General Mohammad Baqeri, whose government backs Syrian President Bashar al-Assad, said Tehran and Damascus would respect the U.N. resolution.
But the Iranian military chief of staff also said the truce did not cover parts of the Damascus suburbs "held by the terrorists", the Tasnim news agency said.
In Ankara, Turkish Deputy Prime Minister Bekir Bozdag said the U.N. resolution would not affect Turkey's offensive against Kurdish fighters in Syria's Kurdish-held Afrin region.
Turkey launched an assault last month on Afrin, seeking to drive out the Syrian Kurdish YPG militia which it deems a menace along its border.
Several ceasefires have unraveled quickly during the seven-year war in Syria, where Assad's military has gained the upper hand with the help of Iran and Russia.
The U.N. resolution on Saturday followed seven straight days of bombing by pro-government forces on eastern Ghouta, in one of the bloodiest offensives of the war.
The Security Council voted unanimously to demand the truce to allow for aid access and medical evacuations. Yet while Moscow supported adopting the resolution, Russian U.N. Ambassador Vassily Nebenzia cast doubt on its feasibility.
The resolution does not cover militants from Islamic State, al-Qaeda, and the Nusra Front.
Baqeri said Iran and Syria would adhere to it. But "parts of the suburbs of Damascus, which are held by the terrorists, are not covered by the ceasefire and clean-up (operations) will continue there," Tasnim quoted him as saying.
The Syrian government and Russia deny hitting civilians. Moscow and Damascus have said they seek to stop mortar attacks by militants injuring dozens in the capital.
The United Nations says nearly 400,000 people live in eastern Ghouta, a pocket of towns and farms under government siege since 2013. It is the only big rebel bastion left near the capital.
The two major Islamist factions in Ghouta said they waged fierce battles on Sunday on several fronts around the enclave, where troops and rebels have clashed in recent weeks.
Hamza Birqdar, Jaish al-Islam's military spokesman, said the rebels thwarted attempts by government forces and Iran-backed militias to advance.
"In the early hours of dawn today, there were heated battles which Assad's forces launched," said Wael Olwan, spokesman for Failaq al-Rahman. "They tried to storm the eastern frontlines. The bombing is ongoing at this moment."
Russia was counting on foreign supporters of anti-government forces to ensure that the ceasefire was observed, the foreign ministry in Moscow said.
Moscow has blamed Nusra fighters from al-Qaeda's former Syria branch for provoking the situation in Ghouta. Both main rebel factions in turn accuse their enemies of using the presence of a few hundred jihadist fighters as a pretext for attacks.
Syrian state media said Ghouta insurgents shelled parts of Damascus. An army unit destroyed a rigged vehicle that militants tried to send into the capital a day earlier and killed the suicide attacker, a Syrian military source said.
Pope Francis described Syria as "martyred" on Sunday, calling for aid access and an immediate end to violence.
"All this is inhuman," Francis told tens of thousands of people in St. Peter's Square for his weekly blessing.
First responders in eastern Ghouta rushed to look for survivors after air raids on Beit Sawa and Saqba, said the Civil Defence service which operates in rebel territory.
A witness in Douma said warplanes were still flying in the morning.
People have holed up in basements to hide from the air strikes in recent days, and medical charities decried attacks on more than a dozen hospitals.
