Airstrike on Syria aid convoy: What we know so far

US and Russia in 'parallel universe' on Syria ceasefire

US Secretary of State John Kerry and Russian counterpart Sergey Lavrov have clashed at the UN over the failed Syria ceasefire.

It follows the attack on an aid convoy in Syria which killed 21 people, which the US blamed on Russia but Moscow has denied any involvement in.

Here are the key developments:

The attack on Monday night left at least 21 people dead, aid agencies said
The aid convoy was delivering aid for 78,000 people at the time of the attack
The United States believes two Russian jets carried out the airstrike, something Russia has denied
At the UN, Mr Kerry appeared to suggest Mr Lavrov was a 'spoiler' who 'shredded' any hopes of a ceasefire
Mr Kerry has also called for no-fly zones to be implemented in Syria
Mr Lavrov said a ceasefire would only work if there was a comprehensive approach with simultaneous steps taken by all parties involved
The UN has said it will resume humanitarian aid convoys within Syria

The United Nations has suspended all aid into Syria after a deadly attack on a convoy carrying humanitarian supplies on Monday.

It came as a week-old US-Russian sponsored ceasefire collapsed in renewed violence.

This is what we know so far:

The airstrikes began at Urum al-Kubra near Aleppo shortly after 7pm local time on Monday, destroying 18 of 31 trucks of aid at delivering food, winter clothes, blankets and educational supplies for 78,000 people.
The attack left 21 people dead, aid agencies said.
It happened as a week-long ceasefire agreement appeared to unravel, with Syria's military declaring the truce to be over.
The UN described the airstrikes as "sickening", and suspended all aid convoys to besieged Syrian towns.
Russia, which is allied to Assad's government, denied that either its air force or that of the Syrian armed forces was responsible. The Russian defence ministry also said it sees "no evidence" that the aid convoy was shot at, suggesting it may have caught fire. The Syrian army also denied blame.
Moscow said there was little hope for a renewal of the ceasefire, but US Secretary of State John Kerry said the ceasefire was "not dead".
