Syria defiant after PM Riad Hijab defection

Civilians have become caught up in further clashes in Aleppo

Syria's new cabinet has begun work, after Prime Minister Riad Hijab defected and denounced Damascus's "terrorist regime".

Information Minister Omran al-Zoubi said Mr Hijab had not yet appeared in person and he rejected reports of other ministerial defections.
Meanwhile, Iran's security chief has made an unexpected visit to Damascus in an apparent step change in diplomacy.
Tehran says it is planning a conference aimed at solving the Syrian crisis.
The staunchest regional ally of Syrian President Bashar al-Assad, Tehran is also trying to secure the release of a group of Iranians abducted by rebels from a bus in Damascus on Saturday.
'US held responsible' An unconfirmed report from the rebels has suggested that three of the 48 hostages they are holding have been killed by army shelling.
Saeed Jalili, who heads Iran's supreme national security council and is considered a senior aide to Supreme Leader Ayatollah Ali Khamenei, was meeting Bashar al-Assad and several other top officials.
It also emerged that Foreign Minister Ali Akbar Salehi was travelling to Turkey for talks in Ankara.
Iran's Deputy Foreign Minister Hossein Amir Abdollahian has said it holds the US responsible for the hostages' safety.
He said the US was supporting "terrorist groups" and despatching weapons to Syria, and was therefore responsible for the lives of those abducted.
The rebels have claimed that the group are members of the Revolutionary Guard. Tehran says they are pilgrims who had been heading for a Shia religious site.
'Business as usual' Caretaker Prime Minister Omar Ghalawanji headed an emergency cabinet meeting on Monday, stressing that all the ministers were there. He was due to chair a further session on Tuesday.

Riad Farid Hijab

• Born in 1966 in Deir al-Zour, eastern Syria
• Married with four children
• Holds a PhD in agriculture
• Joined the local branch of the Baath Party command in 1998
• Named governor of the southern province of Qunaytira in 2008
• Transferred to head the Latakia governorate around the time protests were first reported - credited in state media with negotiating an end to a sit-in
• Appointed minister of agriculture on 14 April 2011

The BBC's Jim Muir, in neighbouring Lebanon, said state media were giving the impression of it being business as usual in Damascus.

Opposition activists said that apart from the prime minister, two other ministers had also defected and a third - Finance Minister Mohammad Jalilati - was arrested as he tried to escape.
But footage of the cabinet on state TV showed two of the ministers who had supposedly defected and Syria's information minister played down the significance of Mr Hijab's departure.
"We haven't heard anything from the former prime minister and he didn't appear on TV," Omran al-Zoubi was quoted as saying by Syrian state news agency Sana.
Syria was a state of institutions, the information minister said, and the flight of some of its individuals would not affect the state, however prominent they were.
But reports of defections have continued, with Turkey's foreign ministry announcing on its Twitter feed that a general was among more than 1,300 refugees who fled across the border overnight.
The number of Syrians who have crossed into Turkey has risen to 47,500, Ankara says.
'Safe location' Riad Hijab, appointed as prime minister less than two months ago, is the most prominent Syrian figure to defect so far.
Although his whereabouts are unclear, his spokesman appeared on al-Jazeera TV in neighbouring Jordan saying that the prime minister had fled Syria with his family and was in "a safe location".
"I have defected from the terrorist, murderous regime and [am] joining the holy revolution," ran Mr Hijab's statement read by his spokesman Mohammed el-Etri.

State media said troops had clashed with "terrorists" in several places in Aleppo

France said the Assad government was "doomed" and White House spokesman Jay Carney said such high-level defections signalled that President Assad's grip on power was "loosening".
On the ground in Syria, clashes have been reported in Aleppo and the army is said to have stepped up its bombardment of the northern city.
Government forces are trying to dislodge rebel fighters who have taken control of up to half of Aleppo.
Opposition activists report intense attacks on rebel-held areas on the north-east and south-west sides of the city.
State media said troops had clashed with "terrorists" in several places inflicting heavy losses.
Further deaths were reported in Damascus on Tuesday. Syrian agency Sana said a "terrorist hideout" had been stormed by security forces.
British-based activist group Syrian Observatory for Human Rights said 270 people were killed across Syria on Monday. It said 61 civilians died in Aleppo province alone.
Activists estimate more than 20,000 people have died since the uprising against President Assad began in March last year.
Reports of casualties often cannot be independently verified as the movement of foreign journalists is severely restricted in Syria.
