What is the Syria ceasefire?
A new ceasefire is underway in the war torn country of Syria in the Middle East.
The deal to stop fighting was agreed between the Syrian government and some rebel groups fighting against them.
There has been a war in Syria since 2011 and since then, it's thought 300,000 people have lost their lives.
Four million people, including children, have been forced to leave the country and seek safety in nearby countries and Europe.
So far, the new ceasefire, which started at midnight on Thursday, seems to be holding, although there have been reports of isolated fighting in some areas.
What is a ceasefire?
A ceasefire is an agreement by opposing sides to stop fighting in a war.
This can be for a certain amount of time as a short break or it can be agreed for a longer period of time.
In this ceasefire in Syria, there are many groups involved.
Syrian government forces, the Free Syrian Army and many rebel groups have all agreed to the ceasefire.
But not all groups operating in the country are part of the deal.
What about Islamic State?
The group that calls itself Islamic State and other extremist Islamist groups, are not part of the ceasefire.
Islamic State have taken over large parts of Syria and neighbouring Iraq and fighting against them is continuing, whilst the ceasefire is underway.
What happens next?
If the ceasefire does continue to hold, then peace talks aimed at ending the war in Syria could be held within a month.
