A wave of suicide bombings by Islamic State militants in western Iraq has killed 40 soldiers amid waning efforts by security forces to retake territory from the Sunni extremist group, a senior Iraqi commander said Monday.
The attacks, which occurred on Sunday in the town of Sijir, 70 kilometers (43 miles) west of Baghdad, dealt a heavy blow to government efforts to rein in the militants whose rampage has seized much of the country's north and west this summer.
