The government of a Nigerian state besieged by Islamic militants has identified 53 girls who have since escaped abduction, a controversial move because the girls could face stigma.

Some 276 girls remain missing, and U.S. officials and agents are arriving in Nigeria to help the government rescue them.

Boko Haram abducted more than 300 girls from a school in Chibok last month.

The government of Borno state said in a statement received Friday that the 53 girls it identified by name include those who fled the day they were kidnapped and those who escaped from Boko Haram camps days later.

Chibok residents are staging a street protest Friday to press Borno's government to do more to find the missing girls.
