The US, UK and other states have pledged aid and humanitarian assistance to help rescue refugees fleeing Isis in northern Iraq.  The US has launched two airstrikes against the Islamic State. The defence secretary, Chuck Hagel, announced on Tuesday that 130 troops were being sent to Iraq as "assessors", joining 450 troops already there.

China's international reputation for humanitarian aid is among the worst of the globe's superpowers. As Quartz reports, the new shipment of millions of dollars in medical supplies and workers could be the beginnings of an attempt to reshape that reputation. Only 0.4% of China's foreign aid goes directly to humanitarian causes, rather that infrastructure projects or business efforts that could serve to improve nations' trade with China as much as it could help the nations themselves. In Africa, particularly, China's actions have appeared self-rewarding rather than altruistic.

The United Nations has warned that a mass atrocity or genocide of refugees in the Mount Sinjar region of northern Iraq could still happen “within days or hours”.  The UN's special rapporteur who has been investigating the plight of 40,000 mainly Kurdish-speaking Yazidis who fled to the mountain fearing attacks from the extremist militants of the Islamic State of Iraq and the Levant (Isis), said the world urgently needed to recognise the severity of the humanitarian crisis.

The Coordination Agency of Public Diplomacy (KDK) published some briefings on the humanitarian aid work carried out in Iraq and Palestine. Data is presented in an info-graphic prepared by the institution and is published in English, French and Arabic.

The political leader of Iraq's Kurds, Massoud Barzani, has appealed for international military aid to help defeat Islamist militants in the north.  The plea came as the US launched a fourth round of air strikes targeting Islamic State fighters near Irbil, the capital of Iraqi Kurdistan.

President Barack Obama authorized targeted airstrikes and emergency assistance missions in northern Iraq, saying Thursday the U.S. must act to protect American personnel and prevent a humanitarian catastrophe in the face of advances by violent Islamist militants. The U.S. military said it completed a delivery of meals and water to thousands of members of a religious minority who fled the town of Sinjar and are trapped in nearby mountains by the group calling itself the Islamic State.

An Obama administration program secretly dispatched young Latin Americans to Cuba using the cover of health and civic programs to provoke political change, a clandestine operation that put those foreigners in danger even after a U.S. contractor was hauled away to a Cuban jail. Beginning as early as October 2009, a project overseen by the U.S. Agency for International Development sent Venezuelan, Costa Rican and Peruvian young people to Cuba in hopes of ginning up rebellion.

Bringing a stable source of electricity to Kandahar, the cradle of the hardline Islamist movement and once a base for its leader Mullah Omar, was a top U.S. "counter-insurgency priority" as Washington pursued its policy of winning "hearts and minds". But regular power in the city is still years away, and when the United States finally ends subsidies - currently running at just over $1 million a month - in September 2015, Kandahar could lose around half its severely limited electricity supplies, Afghan power officials and U.S. inspectors say.
