LAGOS, Sept. 26 (Xinhua) -- The Nigerian federal government has given an assurance of its sincerity about the amnesty it offered to militant groups in the Niger Delta region, the Nigerian Compass newspaper reported on Saturday.

The government's declaration came on the heels of calls by some unrepentant armed youth for an extension of the amnesty period, while some militant leaders have also expressed concerns about the commitment of the government to the terms of the amnesty.

Nigerian Minister of Special Duties Ibrahim Kazaure gave the guarantee after a visit to southwest Nigeria's Ogun State Governor Gbenga Daniel.

According to the minister, President Yar'Adua would consider the calls for the extension of the amnesty period and take a decision without compromising the nation's overall security.

Kazaure said the president has taken personal responsibility for all issues relating to the amnesty deal and would do everything needed for it to succeed.
