In January 2014 a brutal new Jihadist group swept through Syria and set up its capital in Raqqa in the east of the country.
In the two years since, so-called Islamic State has evolved into the most notorious extremist group in the world.
For the past three months, BBC Radio 4's Today programme correspondent, Mike Thomson, has been in sporadic contact with an activist based in Raqqa from a group called Al-Sharqiya 24. This short documentary depicts the activist's diary of what life is like under Islamic State.
