Afghan protesters beat a policeman after a suicide attack that targeted crowds of minority Shiite Hazaras during a demonstration at the Deh Mazang Circle of Kabul on July 23, 2016. Islamic State jihadists claimed responsibility for twin explosions July 23 that ripped through crowds of Shiite Hazaras in Kabul, killing at least 61 people and wounding 207 others in apparently their deadliest attack in the Afghan capital. The bombings during a huge protest over a power transmission line could deepen sectarian divisions in a country well known for communal harmony despite decades of war.

“Locusts & Men”. Oppression, interaction, collaboration. In the life cycle of nature nothing is lost, but the coexistence of different species is sometimes difficult. In Madagascar periodically returns the archaic antagonism between man and the migratory locust, in a circle of life where the two species are looking for space and food for their survival. At the end of the day a man walks home carrying on his shoulders the heavy bag which contains the locusts captured during the day. The insects provide nutritious meals for the man and his family.
