Under the streets of Damascus rebel units are waging a subterranean war against the Assad regime.
Two British men who fled to Syria to fight alongside rebels today admitted preparing acts of terror.
The brother of a British jihadi fighter who featured in an Isis promotional video in Syria says he was not radicalised by his local mosque.
Nine trucks carrying food and other supplies have crossed into Syria through a Turkish checkpoint.
They were the first to do so under a United Nations resolution authorising cross-border aid deliveries without Syrian government approval.
UN spokeswoman Amanda Pitt said the trucks contained desperately needed food, water purification tablets, and sanitation and shelter materials.
The UN humanitarian office has said that if security allows, aid could reach 2.9 million people through the four crossings.
So far more than 150,000 people have died in the three-year Syria conflict.
Former Guantanamo Bay detainee Moazzam Begg has pleaded not guilty to seven terror offences connected with the civil war in Syria.
The 45-year-old appeared via video link from prison to deny the charges.
Begg, of Hall Green, Birmingham, is accused of attending a terrorist training camp in Syria October 2012 and April 2013 and funding terrorism by providing a generator in July last year.
He also faces five counts of possessing an article for a purpose connecting to terrorism between December 31, 2012 and February 26 this year.
Begg will stand trial at the Old Bailey on October 6.
Britain has offered asylum to only 50 people seeking to escape the violence in Syria under a government scheme set up in January, prompting one MP to brand the figure "absolutely shaming".
John McDonnell, Labour MP for Hayes and Harlington, said the level of support being offered to Syrian refugees was "just not acceptable - it's not civilised behaviour ... this is a disgrace".
Security and immigration minister James Brokenshire said the intention of the vulnerable persons relocation scheme was to relocate two to three families a month, working "on the basis of need" rather than to a quota.
He said that the UK had granted asylum to more than 2,700 Syrians since the conflict began in 2011.
Liberal Democrat MP Sarah Teather told a Westminster Hall debate that "a mere 4,084" Syrians had applied for asylum in the UK, adding: "It is a drop in the ocean."
The MP for Brent Central, who led the debate, said that 2.8 million Syrian refugees - half of whom were children - had fled to Jordan, Lebanon, Turkey, Iraq and Egypt.
President Bashar al-Assad called the people of Syria "honourable" and "free" during a speech after being sworn in for a new seven-year term.
He reminded how, throughout the crisis in Syria, some have spoken on behalf of the Syrian people repeating the slogan 'The People Want'.
– President Bashar al-Assad
Yes, the people did want, the people did make their decision, the people did act...Years have passed since some chanted for freedom, but you, the Syrians, were the freemen at the time of subordination, and you were the masters at the time of acting.
Syrian president Bashar al-Assad has been sworn today in for a new seven-year term.
The election, dismissed as a sham by Assad's opponents, underlines his grip on power more than three years into Syria's civil war.
A baby, said to be no more than two months old, has been rescued from rubble in the northern Syrian city of Aleppo, a video posted to YouTube purportedly shows.

Muslim leaders in Britain have condemned the extremist group Isis and say it does not represent the majority of Muslims.
Representatives from both the Sunni and Shia groups in the UK expressed their 'grave concern' as British Muslims continue to travel to the Middle East to join the ongoing violence.
Maulana Shahid Raza, of Leicester Central Mosque told Sky News: "Isis does not represent the main Sunni Muslims' ideology."
Shuja Shafi, of the Muslim Council of Great Britain, said: "Violence has no place in religion, violence has no religion."
William Hague has said that the actions of Isis militants "powerfully demonstrates" why Britain needs to support the Syrian National Coalition, the country's moderate opposition, as he welcomed the election of Hadi a-Bahra as its new president.
– Foreign Secretary William Hague
There can be no peaceful settlement in Syria if the Syrian people are left only with a choice between a brutal regime on the one side and terrorists on the other.
The UK will continue to work closely with president al-Bahra and others in the national coalition and interim government to help achieve their aspirations for a democratic Syria.
Twin teenage girls who are thought to have travelled to Syria are "deeply religious Muslims", police understand.
It is understood an older brother has joined the extremist militant group Islamic State of Iraq and the Levant (Isis), and one line of inquiry is that the girls may have flown out to join him.
The girls, from a large Somalian family, flew from Manchester International Airport to Turkey which borders Syria where the civil war involving Muslim militants is raging.
Greater Manchester Police said the pair had been in contact with relatives since their departure.
