An air strike by a Syrian plane in the northern rebel-held town of Azaz killed 30 people and wounded scores of others, a local doctor said.
The UN Special Envoy to Syria Kofi Annan has admitted he is "frustrated and impatient" over the continued violence and killing in Syria.
So after weeks of insisting his peace mission is the only game in town, it might be that Kofi Annan is preparing to pack up and leave.
Khalid Mahmood, Labour MP for Birmingham Perry Barr has warned that young British Muslims are in danger of being radicalised by the conflict in Syria.
Speaking on the BBC's Today programme Mahmood said he was worried the situation had the potential to radicalise a new generation of jihadists willing to go and fight for the Free Syrian Army. He said:
"I am extremely concerned at the moment because I see similar things to what happened at the original stages of the Afghanistan war where we were supporting the mujahideen against the Russians.
We wanted to get the Russians out and we armed people, we encouraged people to go out there and fight in the jihad"
The UN's Emergency Relief Coordinator, Valerie Amos, has called on the Syrian government and the rebel fighters from the Free Syrian Army to do more to protect the millions of civilians caught up in the 17-month conflict.
Amos said 2.5 million people are now in need of humanitarian assistance. She appealed to the international community to provide more funding, and to the Assad regime to allow NGOs into the country.
More than 40 people were killed and at least 100 others injured in Syrian government air strikes on a residential area of Azaz in Northern Syria yesterday.
So many people were wounded that the local hospital locked its doors, directing casualties to the nearby Turkish border.
Human Rights Watch investigated the site of the bombings two hours after the attack and condemned the Assad regime for displaying a "callous disregard for human life."
Anna Neistat from Human Rights Watch said "this horrific attack killed and wounded scores of civilians and destroyed a whole residential block" and put the death toll at more than 40 people.
The Organisation of Islamic Cooperation suspended Syria's membership at a summit of Muslim leaders in Mecca, citing President Bashar al-Assad's violent suppression of the Syrian revolt as the reason.
Pictures have emerged of the aftermath of an air attack on the rebel-held Syrian town of Azaz.

The air strike has reduced several houses in the town to rubble and dozens of men have clawed through the concrete and metal debris looking for survivors.
The US ambassador to the UN has tweeted her reaction to the UN report into war crimes being committed in Syria:
UN investigators have called for Ban Ki Moon to send their report to the Security Council to take appropriate actions given the gravity of crimes by all sides.
Investigators have also said that they will update their list of people and units suspected of crimes against humanity to the UN rights chief Navi Pillay.
