A Dutch appeals court has ruled that the Nigerian branch of oil giant Shell is responsible for damage caused by leaks in the Niger Delta.

The court ordered Shell Nigeria to pay compensation to Nigerian farmers, while the subsidiary and its Anglo-Dutch parent company were told to install equipment to prevent future damage.

A group of farmers launched the case in 2008, alleging widespread pollution.

However, Shell says the leaks were the result of sabotage.

In responding to the ruling, Royal Dutch Shell said it was disappointed with the verdict, while many human rights and environmental groups have welcomed the ruling which can be appealed against.

Here are excerpts of proceedings from the Hague court.
