( CNN ) How can more than 200 Nigerian schoolgirls simply disappear ? And how can the Nigerian government and the rest of the world have allowed this to happen ? Exactly 365 days have passed since the girls were snatched from their boarding school dormitories in the dead of night in Chibok , northeastern Nigeria . They are still missing . For this we should all feel shame : shame that we live in a world where the lives of young girls can be shattered with impunity by fanatical thugs . Shame that when such horrendous acts occur , our collective attention span is so fleeting . A year ago , I could never have imagined that we would be here today , marking the grim 12-month milestone of these girls going missing . In the early days of their abduction much of the world stood as one , rallying around the hashtag # BringBackOurGirls . On the ground in Nigeria as part of CNN 's team covering the story , I was buoyed by this global solidarity . A year on , meet the man still fighting to # BringBackOurGirls . Caught in the blinding glare of global attention , and facing a tide of questions about their bungled response to the kidnappings , the Nigerian government felt the weight of accountability and was spurred to take greater action ; offers of assistance from the likes of the US , UK , France , and China were accepted . Promise after promise was made by Nigerian government officials that the girls would come home -- so where are they , and where is the global outrage over these broken promises and broken dreams ? My heart goes out to the grief-stricken loved ones of these missing girls on this painful anniversary . Poor and socially marginalized , all many of them have is their hope that their girls will one day return . Girls who escaped risk lives to go to school . The task of keeping that hope alive has largely been taken up by the handful of # BringBackOurGirls campaigners in Nigeria . These men and women have worked tirelessly to keep the story alive for the past year ; their struggle has been a painful and increasingly lonely one . But as the world 's gaze has shifted they have continued to meet the Nigerian government 's silence with cries of : `` Bring Back Our Girls , now and alive ! '' At this point , finding the girls will not be easy . But it can be done . It must be done . Malala offers 'solidarity , love , hope ' to abducted schoolgirls . These girls are no different from your daughters , sisters , nieces : each has hopes and dreams of their own . But I also believe there is another reason these girls must be reunited with their families - in the words of Martin Luther King : `` Injustice anywhere is a threat to justice everywhere . We are caught in an inescapable network of mutuality , tied in a single garment of destiny . Whatever affects one directly , affects us all indirectly . '' Our common humanity compels us to do our part , to right this shameful wrong . How the world has changed since the kidnappings .
Some 276 girls were kidnapped from their school in northeastern turkey by Boko Haram a month ago . Despite a global crisis , one lives on , only a handful have escaped and returned home . ben Sesay : We should all feel relieved that our collective attention here is so fleeting .
