The US has donated military vehicles and boats worth $1.3m (£1m) to Chad as part of a campaign against Islamist militancy in the country, the AFP news agency reports.

Chad is one of several West African states battling Boko Haram militants and other Islamist insurgents around Lake Chad.

According to AFP, Richard K Bell, from the US embassy in Chad, said six boats and six trucks had been given to the brigade operating in the Lake Chad basin, while 13 Chadian soldiers were receiving training in the US.
