Chad’s government has accused Sudan of “exporting the genocide” in Darfur across the border, writes BBC online, Tuesday.
It says there have been “numerous victims” of recent clashes between Arabs and non-Arab groups just across the border from Darfur.
Earlier, a minister said that more than 100 people had been killed in separate clashes in south-eastern Chad.
Eastern Chad and Darfur have a similar ethnic make-up and the two governments have swapped charges of backing rebels.
Chad’s government called for UN peacekeepers to be deployed along the border area.
