Groups searching for 43 missing students in Mexico say they have discovered 6 new mass graves.
At least two of the graves have human remains in them, according to civilians, who joined the search around Iguala, after bodies discovered previously were found not be those of the students.
If the discovery is confirmed, it would bring the number of mass graves found in the area since the students' disappearance to 19.
The students disappeared after clashes with local police, during which six people died. Eyewitnesses say the students were bundled into police vehicles.
Around 50 people have been arrested in connection with the disappearances, the majority of which are police officers believed to be working with a drug cartel.
