Hundreds of Nigerian militants today surrendered their weapons, mortar bombs and gun boats, as part of a federal amnesty programme that aims to stem unrest in the oil-rich Niger Delta, Reuters reported. The handover by three militant gangs was the largest collection of weapons and ammunition since a 60-day amnesty programme began two weeks ago. "We give up our weapons so that we give peace a chance and for all oil companies and other multinationals to come into our region to develop the place," said Erepamutei Olotu, locally known as General Ogunbos, during a public handing over ceremony at an amnesty centre in the Bayelsa state capital Yenagoa.
