Peace talks aimed at bringing an end to the war in Syria will start today.
The talks in Switzerland bring the Syrian government face to face with the people who want them out of power for the first time.
More than 100,000 people have died in the conflict since 2011.
The fighting started when rebel groups tried to overthrow President Assad.
