KUWAIT - The Islamic Development Bank (IDB), the largest development organisation in the Muslim world, is ready to finance Iraq infrastructure with $500 million, its president Bandar Hajjar said in Kuwait on Wednesday.

Donors and investors have gathered in Kuwait to discuss efforts to rebuild Iraq's economy and infrastructure as it emerges from a devastating conflict with Islamic State militants who seized almost a third of the country.
