Turkish Prime Minister Ahmet Davutoğlu has discussed the crisis in Syria and Iraq with U.S. President Barack Obama on Saturday, according to the Turkish Prime Ministry.

On the sidelines of the ninth meeting of the 2014 G20 summit in Australia's eastern coastal city of Brisbane, the leaders discussed the recent developments in Syria and Iraq in view of the threat from the militant group ISIS.

Davutoğlu had welcomed, in his Friday remarks in Brisbane, the media reports that U.S. President Barack Obama was asking his advisers to review their strategy Syria strategy.

As the both leaders discussed the recent developments in Syria and Iraq, Obama and Davutoğlu agreed on the fact that the ISIS could not be defeated unless Syrian President Bashar al-Assad was toppled.

The Turkish premier stressed that Turkey has long argued that an integrated strategy was needed to solve the Syrian crisis rather than a "point and selective strategy" like the airstrikes being conducted by the U.S.-led coalition in the Syrian town of Kobani, and throughout Syria and Iraq.

The U.S.-led international coalition, which includes France, Germany, and Saudi Arabia, has been pounding ISIS targets in Iraq and Syria.

During the G20 summit, Turkey announced that the country has pledged to donate $6 million to aid the battle against the current Ebola outbreak in West Africa, as The World Health Organization(WHO) announced on Friday that 5,177 people had so far died of deadly disease across eight countries since late December 2013.

Davutoğlu also thanked Obama for his speech in Myanmar on Thursday where he called on the country's leaders to scrap a controversial plan that aims to force the minority Rohingya Muslims to identify as Bengalis - a term favored by the government because it implies the group are illegal immigrants from Bangladesh.

The Myanmar government's Rakhine State Action Plan offers the chance of citizenship to roughly 1 million Rohingya Muslims - one of the most persecuted minorities in the world according to the United Nations. But they will only be eligible if they identify themselves as "Bengali," despite evidence they have lived in Myanmar for generations.

Obama urged the government to draw up a new plan to allow Rohingya Muslims to become citizens.

Still, according to the Turkish Prime Ministry, Davutoglu had meetings with U.S. President Barack Obama, Russian President Vladimir Putin, U.K Prime Minister David Cameron, French President Francois Hollande, German Chancellor Angela Merkel, Japanese Prime Minister Shinzo Abe along with South Korean and Indonesian leaders.
