Iraqi security forces found the burned bodies of 12 policemen when they recaptured a town north of Baghdad from militants on Saturday, a police colonel and a doctor said.
Troops backed by tribal militia recaptured Ishaqi in Salaheddin province as they readied a fightback against the offensive that saw Sunni Arab militants overrun a large chunk of northern and north-central Iraq this week.
It was one of the closest points to the capital that the militants had reached in the assault they launched in second city Mosul late on Monday.
