AMMAN/GENEVA (Reuters) - A planned Arab League visit to Syria on Wednesday to convey concerns over a crackdown on protests against President Bashar al-Assad's rule has been delayed, an Arab diplomat said, in a sign of Syrian unease at a toughening of the Arab position.
Pro-democracy demonstrations have gathered force in suburbs and rural areas across the country of 20 million despite daily reports of killings of civilians and heavy security in city centres.
Activists said 20 people had been killed on Monday and Tuesday and the United Nations estimates more than 2,200 people have been killed since unrest began in March.
Syria, which faces new sanctions from the European Union and wider Western pressure for Assad to go, had criticised the Arab League's decision late last month to urge an end to attacks on protesters and political and economic reforms.
An Arab diplomat at the Cairo-based League, who asked not to be identified, told Reuters late on Tuesday the visit by Arab League chief Nabil Elaraby had been delayed but not cancelled. "It will take place when conditions permit," he added without elaborating.
Egypt's state news agency MENA said the delay followed a request from Syria, which gave no explanation and did not fix a new date for the trip.
The International Committee of the Red Cross said on Tuesday it was seeking access to thousands of demonstrators believed to be in informal lockups, a day after announcing Syria had opened its prisons for the first time.
ICRC chief Jakob Kellenberger said ICRC staff were making further visits to Damascus central prison, which has 6,000 inmates, both criminal and political.
"We have enough information to know that there are (other) places we have to see as early as possible," Kellenberger told a news conference on his return from Syria where he held talks with Assad.
Prison visits were an "ambitious and delicate exercise" for any country, Kellenberger said, noting that neither Egypt nor Bahrain had granted them despite repeated ICRC requests.
"The Syrian authorities are well aware, including President Assad, that for the ICRC this is a first step. And they are well aware of the fact that we want to go further and beyond," Kellenberger said, declining to be more specific.
The European Union, which imposed a ban on purchases of Syrian oil on Sept. 3, was working on a new round of sanctions, the French foreign ministry said on Tuesday, to target entities that enable the "daily repression" against civilians.
At least one civilian was killed at a roadblock in the restive town of Rastan north of the city of Homs on Tuesday, activists said, while a local activist in Homs was quoted as saying the bodies of five murdered civilians were found there.
Rights activists said there were further arrests around the country on Tuesday with dozens of people detained in the Masbah al-Shaab neighbourhood of the port city of Latakia, which has been besieged by troops and armour for weeks.
In the mostly Ismaili city of Salamiya east of Hama, a doctor, Taj Eldin Zino, was arrested by secret police as part of a campaign against dissidents in Syria's professional class. Security forces also raided houses in the southern town of Nawa.
Rights campaigner Adel al-Hafiya, a member of the Damascus Declaration umbrella opposition group, was arrested in the eastern city of Deir Zor, capital of a tribal province bordering Iraq's Sunni heartland, and taken to an unknown location, said the Local Coordination Committees, a grassroots activist group.
RIGHT TO TREATMENT
Kellenberger said he had made clear to Assad and Syrian officials at every level that all wounded and sick people must receive medical treatment, as required under international law.
"It is about concrete measures we feel have to be taken to ensure this right of everybody -- and I underline 'of everybody' -- to medical care," he said.
"It is for me very important that all medical staff, especially doctors, be they in public or private clinics, be really in a position that they can do their medical duty without any fear," he added.
Human rights campaigners say Syrian forces have arrested tens of thousands of people since the uprising demanding political freedom and an end to 41 years of Assad family rule erupted in March, with many being housed in security police buildings off limits to the ICRC.
Kellenberger vowed to expand ICRC operations in Syria, where it is the only humanitarian agency to deploy international staff, with 16 expatriates there at this time.
"Being realistic we know that we have to proceed step by step," he said. "We will do whatever we can to enlarge further, gradually, our assistance and protection activities."
UNOFFICIAL JAILS
A Syrian lawyer, who did not want to be identified for fear of reprisals, said the Red Cross needed to have access to unofficial jails and detention centres to see torture chambers and the extent of human rights violations in Syria.
"The Damascus central prison is mostly for criminal, not political cases. The bulk of the ugliest torture takes place in the cellars of secret police branches spearheading the repression, such as Military Intelligence and Air Force Intelligence," he said.
Syrian authorities do not reveal the number of detainees in but have previously denied torture allegations and said that any arrests were made in compliance with the constitution. An ICRC spokeswoman said on Tuesday that there was no comprehensive figure for the number of Syrian detainees.
Faced with a heavy security presence in central neighbourhoods of Damascus and Aleppo, and military assaults against a swathe of cities from Latakia on the coast to Deir al-Zor in the East, street rallies calling for an end to the Assad family's domination of Syria have intensified in towns and villages.
Demonstrators have been encouraged by the fall of Libya's Muammar Gaddafi and growing international pressure on Assad. The European Union has imposed an embargo on Syrian oil exports, jeopardising a major source of revenue for Assad, who inherited power from his father, the late Hafez al-Assad, in 2000.
