Thousands of people are reported to have fled recent ethnic and religious fighting in central Nigeria.
Local media reported fighting on Tuesday between Muslims and Christians in six remote farming villages between Plateau and Taraba states.
According to the Nigerian Red Cross many were wounded and killed but few confirmed details are available.
Muslim Fulani cattle herders and Christian Tarok farmers have been clashing for more than two months.
They are fighting mainly over land and cattle.
The Nigerian authorities are wary of confirming death tolls, for fear of fuelling more reprisals.
But a Red Cross official was quoted by Reuters news agency as saying: "It must have been more than 100, but we cannot confirm a specific number of dead."
In 2001 more than 1,000 people died in clashes in the Plateau State capital, Jos.
