Explanation, Please

I am listening to end of Ramadan prayers. I have been wondering about something which I find puzzling. Why is there a rise in suicide and other bombings, and killings even against fellow Muslims during this time of prayer and fasting? I just want to understand the connection between Ramadan and death. Can someone tell me, please? 800 people were killed in Iraq during Ramadan, according to France24. And, that is only one country.
