Officials in Niger say 11 people have been killed in three separate jihadist attacks in the west of the country.

The militants arrived in villages on motorbikes on Wednesday.

They stole livestock, set classrooms on fire and looted a health centre.

This is the second time the three villages have been attacked this year.

There has been a significant increase in Islamist attacks in Niger.

On Sunday, nearly 140 people were killed by suspected jihadists in the north of the country.
