Detailed Explanation:

Amnesty International is a global human rights movement and non-governmental organization (NGO) founded in 1961 with over 7 million members worldwide.

It campaigns for the protection of human rights enshrined in the Universal Declaration of Human Rights, focusing on issues like freedom of expression, abolition of death penalty, refugee rights, and prevention of torture—it is not a UN agency nor specifically focused on poverty alleviation or medical emergencies.
