TOPSHOTS Women and children fleeing from Boko Haram attacks sit at Kabalewa Refugees Camp, Diffa in Niger Republic, on March 13, 2015. Governor of northeastern Nigerian Borno State Kashim Shettima recently visited refugee camps where Nigerians fleeing from Boko Haram Islamists attacks are sheltered in Diffa province of Niger Republic. More than 13,000 people have been killed and some 1.5 million made homeless in the Boko Haram conflict since 2009, while recent cross-border attacks from Boko Haram bases in Nigeria on neighbouring countries have increased security fears.
