A British school teacher in Sudan has been charged with insulting Islam and inciting religious hatred by allowing young children to name a teddy bear Mohammed.
Ms Gibbons may be flogged and jailed if convicted.
British Foreign Secretary David Miliband wants to see the Sudanese ambassador urgently over the decision to press charges.
Gillian Gibbons has been in custody for three days. She was arrested after parents complained that she was insulting the Muslim Prophet by allowing pupils to name the bear Mohammed.
Ms Gibbons has said she never meant to cause offence.
The sentence for publicly insulting or degrading any religion is up to six months in prison, 40 lashes and a fine.
Ms Gibbons, who is in her 50s and has two children, has told British officials that she is being treated well.
