Syria: Arab League sets deadline to end 'repression'
The Arab League has given Syria three days to "stop the bloody repression" of protesters and allow in teams of observers.
Qatari Foreign Minister Sheikh Hamad Bin Jassim al-Thani said Syria faced sanctions if it did not co-operate.
At a meeting of the Arab League in Morocco, he said diplomatic efforts were "close to the end of the road".
As the meeting took place, angry crowds in Damascus attacked the embassies of Morocco and the United Arab Emirates.
Morocco responded by recalling its ambassador to Syria, AFP news agency reported.
Hours earlier - in another sign of Syria's increasing international isolation - France also said it was withdrawing its ambassador.
Foreign Minister Alain Juppe told parliament: "There has been renewed violence in Syria, which has led me to close our consular offices in Aleppo and in Latakia as well as our cultural institutes and to recall our ambassador to Paris."
Sheikh Hamad, asked if the Arab League proposal was a last-ditch attempt at diplomacy, told a news conference in Morocco: "We do not want to talk about a last-ditch attempt because I do not want this to sound like a warning.
"What I can say is that we are close to the end of the road as far as the (Arab League's) efforts on this front are concerned."
The statement came hours after reports that rebel Syrian troops had attacked a major military base near Damascus.
Turkey, although not a member of the Arab League, sent its Foreign Minister Ahmet Davutoglu to a Turkish-Arab co-operation forum on the fringes of the league's meeting in Rabat.
Turkey, which shares a long border with Syria, has been increasingly critical of President Bashar al-Assad's repression of anti-government protests.
In a joint statement, they demanded "urgent measures... to ensure the protection of civilians" and declared they were against "all foreign intervention in Syria".
Last weekend the Arab League voted to suspend Syria's membership after it failed to honour the terms of an Arab League peace plan.
The plan involved Syria withdrawing tanks from restive cities, stopping attacks on protesters and engaging in dialogue with the opposition within two weeks.
But since then violence across Syria has escalated.
Syrian activists say defected soldiers known as the Free Syrian Army launched a pre-dawn attack on the notorious Air Force Intelligence building in the Damascus suburb of Harasta.
Unconfirmed reports said six government soldiers were killed.
Correspondents says such an attack would be the highest profile operation so far by renegade troops.
The Commander of the Free Syrian Army, Ryad al-Asa'ad, who is based in Turkey, told the BBC Arabic Service the international community had let them down in their fight against the regime.
"At the moment no country in the world has helped," he said.
"All of them, every country has refused. Even Turkey has never offered us even one bullet and has even completely banned operations on the border, or on the road to the border. On the other hand, we are from inside Syria, we work inside Syria and the weapons are from Syria."
He said defections were increasing within the Syrian army.
"Thank God, there is a big number [of defectors] the number increases daily. Now, over the past 10 days, defections have been increasing in a very very big way, even officers, a great number are defecting."
Meanwhile, anti-government activists reported further bloodshed across Syria on Wednesday.
The Local Co-ordination Committees (LCC) said 11 people had been killed in Homs, seven in Idlib and one each in Daraa and the suburbs of Damascus.
The London-based Syrian Observatory for Human Rights said on its Facebook page that three defectors and a civilian were shot dead in Keferzita, Hama province.
Some 376 people had been killed since the announcement of the Arab League initiative on 2 November, the LCC said.
The UN says more than 3,500 people have died since protests started in March. Syrian authorities blame the violence on armed gangs and militants.
The Syrian government has severely restricted access for foreign journalists, and reports are difficult to verify.
