The Niger Delta Avengers have pledged to lay down their weapons and resume talks with the Nigerian government after months of attacks on the country's oil and gas infrastructure that have crippled the economy.

In a message posted on the group's website late on Saturday, the NDA said it would "observe a cessation of hostilities" in the Niger delta and would support any effort to negotiate with "the federal government of Nigeria, representatives from the home countries of all multinational oil corporations and neutral international mediators."
