An activist in ISIS-controlled Raqqa has been sharing his experience  about life under the extremist group.

BBC Radio 4 's "Today" program has published animated videos that share a bit of the activists experience, highlighting many of the daily horrors of life under ISIS. Working with an activist group called Al-Sharqiya 24, the activist's identity has been hidden by the radio program for his protection.

Sobering and horrifying, the "Life Inside 'Islamic State'" animations reveal a glimpse of the terrors that ISIS regularly inflicts on those under its control.

In Diary 1, the activist talks about when ISIS first entered Raqqa ...

He describes the horrors of the invasion and watching public beheadings and lashings as well as being lashed himself for cursing out loud.

In Diary 2, the man talks about joining the activist group and seeing severed heads posted on fences

Continuing, he explains the horrors of a Russian airstrike in which many civillians are killed.

The only meaning of life becomes simply staying alive, according to the activist's third diary

Collectively, the animated diaries paint a grim yet vivid picture of the reality that thousands are forced to live with every day. You can watch the series of videos on BBC Radio 4's website .
