BAGHDAD (Reuters) - Iraqi government forces backed by helicopter gunships began an offensive on Saturday to retake the northern city of Tikrit from Sunni Islamist militants while party leaders pursued talks that could end Prime Minister Nouri al-Maliki's divisive rule.

Politicians in Baghdad and world powers warn that unless security forces recover cities lost to the jihadi insurgents in tandem with a rapid formation of a government that can bring Iraq's estranged communities together, the country could rip apart along sectarian lines and menace the wider Middle East.
