The United Nations has more than 100,000 peacekeepers, serving in 16 missions on four continents.

Their goal is to protect civilians and maintain peace and security.

But their operations have caused controversy, including allegations of sexual abuse.

Demand for peacekeepers in conflict zones continues to rise and the UN is struggling to keep up.

Defence ministers from more than 70 countries flew to London to discuss how to improve operations.
