Islamic State kills almost 1,900 in six months

The Islamic State militant group has killed 1,878 people in Syria during the past six months, the majority of them civilians, a British-based Syrian monitoring organisation said.

Islamic State also killed 120 of its own members, most of them foreign fighters trying to return home, in the last two months, according to the Syrian Observatory for Human Rights.

The militant group has taken vast parts of Iraq and Syria and declared a caliphate in territory under its control in June. Since then it has fought the Syrian and Iraqi governments, other insurgents and Kurdish forces.
