Two British women have had acid thrown in their faces in Zanzibar, police on the east African island say.
Katie Gee and Kirstie Trup, both 18 and from London, were working as volunteer teachers on the island.
Their mothers, Nicky Gee and Rochelle Trup, said they expected them to return to the UK on Thursday night.
The Foreign Office said it was "concerned to hear of an attack on two British nationals" and was "providing consular assistance".
