Suicide bombings, improvised explosive devices and combatants with little regard for the rules of war are making the work of nearly 125,000 U.N. peacekeepers look more and more like counterterrorism operations. Some U.N. member states balk at sending their troops into such conditions to protect civilians. Others ask how heavily armored U.N. troops can promote peace. And new allegations of sexual abuses by U.N. peacekeepers expose deep gaps in training and accountability. (AP Photo/Petros Karadjias, File)
