Pope Francis begins a visit to Turkey on Friday with the delicate mission of strengthening ties with Muslim leaders while condemning violence against Christians and other minorities in the Middle East.
Turkey and the United States smoothed over some differences in the fight against Islamic State during a weekend visit by U.S. Vice President Joe Biden, but the talks heralded little in the way of deeper military cooperation between the NATO allies.
The coalition fighting Islamic State must now save Syria's second city Aleppo as moderate rebels face destruction by attacks from forces loyal to President Bashar al-Assad and jihadi militants, France's foreign minister said.
