Syrian forces killed at least 17 people in raids near the Lebanon and Turkey border and in the country's Sunni tribal heartland, activists said, pursuing a military campaign to crush street protests against President Bashar al-Assad.
Assad's forces have intensified assaults on towns and cities across the country since the start of Muslim fasting month of Ramadan to subdue mounting dissent against the ruling family, from Syria's minority Alawite sect, despite threats of new U.S. sanctions and calls from Turkey, Syria's powerful northern neighbor, and Arab nations, to halt the attacks.
Activists and rights campaigners said 11 civilians, including a woman and a child, were killed Thursday when troops backed by tanks swept into Qusair, 85 mile north of Damascus, after overnight protests calling for Assad's removal.
In nearby Homs, activists said Friday three people were killed in an overnight raid on the Byada residential district following protests in the city.
Nightly Ramadan prayers, which follow the breaking of the fast and known as 'tarawih', have presented a venue for more Syrians to march in daily protests against 41-years of Assad family rule across the country of 20 million, activists said.
Syrian authorities have expelled most independent journalists since the five-month uprising, making it difficult to verify accounts on the ground.
In the east, troops and members of the feared Military Intelligence, backed by tanks and armored vehicles, expanded assaults in Deir al-Zor, capital of an oil producing province bordering Iraq's Sunni heartland.
Four civilians were killed in house to house raids in Deir al-Zor Thursday and several shops belonging to families of prominent dissidents in the city were torched, the Syrian Observatory for Human Rights said.
One person was also killed in the coastal city of Latakia.
In Saraqeb, a town on Syria's main north-south highway and near the Turkish border, has seen daily demonstrations. Around 14 tanks and armored vehicles also swept into the town. One hundred people were arrested by the security forces, residents said by telephone.
The tanks later withdrew and residents took to streets in a night rally, but security forces fired at the demonstrators, injuring four, the Syrian Observatory said.
The U.S. imposed new sanctions on Wednesday, and a flurry of foreign diplomats have rolled through Damascus urging Assad to end a campaign of killing that rights groups say has left about 1,700 dead since mid-March. Turkey's foreign minister, a day after meeting with Assad, on Wednesday renewed his condemnation of the attacks.
The White House said President Barack Obama spoke with Turkish Prime Minister Tayyip Erdogan to underscore his deep concern about the Syrian government's use of violence against civilians.
It said the two agreed on Thursday that the violence in Syria must stop and that the demands of the Syrian people for a transition to democracy must be met. Obama and Erdogan agreed to consult closely on the situation in the coming days.
Secretary of State Hillary Clinton, asked in a CBS interview why the United States has not yet called for Syria's president to step down, said Washington wants other nations to add their voices.
Clinton also said what was really necessary to pressure Assad was to sanction Syria's oil and gas industry, saying "we want to see Europe take more steps in that direction."
The United States has been "very clear" in its statements about Assad's loss of legitimacy, Clinton said.
Medical facilities attacked
A U.S.-based international human rights groups released a report Wednesday night accusing Syrian authorities of targeting medical facilities, health workers and their patients. It called on the government to safeguard doctors' obligations to provide neutral and ethical care for civilians.
Physicians for Human Rights said security forces control access to hospitals, and many injured civilians in need of critical care are forgoing treatment because they fear being detained and tortured if they seek care at government-controlled medical facilities.
"In addition to the widely reported atrocities committed by the government, PHR has received reports of serious violations of medical neutrality in Syria," a statement by the group said.
It also quoted a group of Syrian physicians as saying 134 doctors have either been detained by the government or have disappeared.
In a continuing nationwide campaign of arrests, Syrian activists said Thursday that security forces detained Abdul-Karim Rihawi, the Damascus-based head of the Syrian Human Rights League. A longtime rights activist, Rihawi had been tracking government violations and documenting deaths in Syria.
The attack on Saraqeb is particularly noteworthy because it sits in Idlib, a province bordering Turkey. Intense protests in the area triggered a harsh government response, forcing hundreds of Syrians to flee across the border. The military on Wednesday said it withdrew from residential districts in the area and returned to its barracks.
The military also said this week it withdrew from Hama in central Syria, following a weeklong military siege and military operations in the defiant city.
A group of Turkish journalists who toured Hama for four hours Thursday saw two APCs parked at the main square keeping watch over the city center and soldiers on some streets, but no tanks or heavy weaponry in sight.
"The soldiers and security forces destroyed everything, they didn't leave anything. We are in God's hands," one man they spoke to said, speaking on condition of anonymity for fear of reprisal.
Another person said everything was calm and urged residents who escaped Hama to return.
The military action came a day after the information ministry ferried local journalists to Idlib. A senior army officer told reporters that troops were withdrawing to their barracks, leaving residential districts in the province's cities.
On the same day, Syrian security forces shot dead at least 15 people in the central flashpoint city of Homs, according to the LCC.
The government justified its attacks on various cities by saying it was dealing with terrorist gangs and criminals who were fomenting unrest.
The uprising was inspired by the revolutions and calls for reform sweeping the Arab world, and activists and rights groups say most of those killed have been unarmed civilians. An aggressive new military offensive that began with the Ramadan at the start of the month killed several hundred people in just one week.
The London-based observatory said authorities on Wednesday night detained opposition figure Hassan Zahra during a raid in a Damascus suburb. Zahra, a 67-year-old member of the Communist Action Front, was detained at least once since the uprising began, it said.
International condemnation over the crackdown has been strong, and growing more forceful.
Turkey calls for peace
In Turkey, Foreign Minister Ahmet Davutoglu renewed calls Thursday for an end to the bloodshed and said Turkey would be closely watching developments there.
"Of course, it is difficult to expect this when tensions are so high, but our expectation is that measures are taken to prevent the loss of lives, for civilian losses to end. We will be monitoring closely."
The Obama administration, which announced new sanctions Wednesday, is preparing for the first time to explicitly call for Assad to step down, officials have told the AP. The moves are a direct response to Assad's decision to escalate the crackdown by sending the army into opposition hotbeds.
The new sanctions affect the state-owned Commercial Bank of Syria and its Lebanon-based subsidiary, the Syrian Lebanese Commercial Bank, for what the U.S. says are their links to human rights abuses and to illegal weapons trade with North Korea.
Mobile phone company Syriatel was targeted because it is controlled by "one of the regime's most corrupt insiders," said David Cohen, the U.S. Treasury Department's undersecretary for terrorism and financial intelligence.
The action freezes any assets the firms have in U.S. jurisdictions and bans Americans from doing business with them. But they may not have much immediate economic impact because the U.S. already severely limits trade and economic ties with Syria.
