(CNN) -- At least three people were killed and 14 people were wounded after an explosion at a mosque in Maiduguri, Nigeria, a spokesman for the Red Cross said Friday.
The blast took place just after 2 p.m. when prayers ended at the central mosque in the northeastern city.
The injured were taken to State Specialist hospital, Red Cross Spokesman Andronicus Adeyemo said.
Christians and Muslims militant groups have attacked each other's religious sites in recent weeks, saying they were in retaliation for prior attacks.
On June 17, at least 50 people were killed at three churches. Boko Haram, a militant Islamist group, claimed responsibility.
