'He took huge risks to get to the truth': rights activist Patrick Naagbanton dies

Tributes paid to the inspirational Nigerian campaigner and writer, who was hit by a car outside his home in Port Harcourt

A leading activist, journalist and writer who fought for the environmental rights of Nigerians in one of the most polluted places on earth has died after being hit by a car.

Friends and colleagues of Patrick Naagbanton described him as highly respected in the Niger Delta, Africa's most important oil-producing region. They said his death, and the absence of his work holding the government, companies and individuals with interests in the region to account, would leave an enormous hole.
