At least 113 Iraqi troops and PMF members were killed in the attacks on Thursday, while another 106 were injured. ISIL seized Anbar's capital Ramadi two months ago, extending its control over the Euphrates valley west of Baghdad and dealing a major setback to Abbadi and the US-backed army he entrusted with its defence. The fall of Ramadi was the Iraqi army's worst defeat since ISIL swept through north Iraq last summer.
