REPUBLIKA.CO.ID, BAGHDAD -- Arab nations rallied Tuesday behind US efforts to form a broad coalition against jihadists in Iraq and Syria as Secretary of State John Kerry headed to the region to cement their support.

Regional heavyweight Saudi Arabia is to host talks Thursday between Kerry and ministers from 10 Arab states and Turkey on joint action against the Islamic State group.

The moves came as Britain announced it was shipping $2.6 million (two million euros) worth of weapons to Kurdish forces fighting the jihadists in Iraq.

Kerry's expected arrival in the region Wednesday comes with Washington buoyed by the formation of a new government in Baghdad.

It will coincide with a keenly awaited speech by President Barack Obama in which he has vowed to set out a strategy to defeat the jihadists whose wave of atrocities has shocked the world.

Iraq's campaign to claw back the territory it lost in the Sunni Arab heartland north and west of Baghdad in June, and US efforts to engage Sunni governments in the fightback, have been complicated by regional sectarian politics.

Saudi Arabia and the five other Gulf Arab states had deeply strained relations with the Shiite-led government in Baghdad, with each side blaming the other for the jihadists' advance.

But their foreign ministers will be among those attending Thursday's talks in the Saudi city of Jeddah, along with top diplomats from Egypt, Jordan, Lebanon, Turkey and Iraq itself.

They will address "terrorism in the region, extremist organisations behind it and means of fighting them," Saudi state media said.

The Arab League, which has stopped short of explicitly backing ongoing US air strikes against IS, also drummed up regional support for the fight.
