BAGHDAD - An Iraqi lawmaker has called on her government to investigate a suspected air strike at a Shi'ite mosque during fighting in nearby Kirkuk last week, saying US-led forces could have been involved - a suggestion dismissed by the coalition.Human Rights Watch echoed the call from Shi'ite Muslim MP Hanan al-Fatlawi for an inquiry, saying on Monday only Iraqi and US-led coalition forces were known to carry out air attacks in the region. Iraq's army said it was investigating.The multiplication of forces involved in the conflicts in Iraq and neighboring Syria has raised fears of accidental strikes and confrontations on an increasingly complex battlefield.
