Does the Muslim world have the leaders it needs?

As more than 30 leaders from Islamic countries gather in the Turkish city of Istanbul, the main message has been one of unity.

But many say it's hard to disguise the fact the Muslim world is deeply divided.

The leaders of two of the biggest countries in the Middle East, Saudi Arabia and Iran, are locked on opposing sides of the conflicts in Syria and Yemen.

Meanwhile, the Islamic State of Iraq and the Levant (ISIL) and its ideology threatens to destabilise or consume nations around the world.

And hundreds of thousands of refugees from the Muslim world are being forced to uproot their lives and relocate to an increasingly unwelcoming Europe.

It's against this backdrop that the Organisation of Islamic Cooperation summit is being held.

An organisation that prides itself on being the collective voice of the Muslim World. But is it doing its job?

And can its leaders overcome divisions to find solutions for the many challenges facing the Muslim world?
