Today is the 100th day since the Nigerian schoolgirls from Chibok were kidnapped by Boko Haram. Vigils are taking place around the world – and we will be covering the events as they happen in words, pictures and social media, updating this blog as the day goes on.

Supporters will light candles and stand in solidarity in Africa, Asia, Europe and the United States. The Bring Back Our Girls group will play a leading role, with events organised in the Nigerian capital Abuja. Marches will be held across the country and prayers will be said in churches and mosques.

As well as Nigeria, events are being held in other countries including Pakistan, India, Bangladesh, Togo, the United Kingdom, the United States, Canada and Portugal. Some events will also be held tomorrow – July 24 – and we will also cover those on this page.

You can also:

Sign a new online petition by A World at School – using the form on this page – which will call for the safe return of the girls. You can also leave a message of support along with the petition and these will be passed to Chibok community leaders and families of the girls.
