Abubakar spoke on Monday. Other officers on Tuesday told The Associated Press that the navy is in pursuit of the captured vessel. The officers, who spoke on condition of anonymity because they are not authorized to speak to the press, said the hijackers have given the government 31 days to free Kanu or say they will blow up the ship along with its crew.
Maritime industry reports indicated the vessel was an oil tanker seized about 100 miles (160 kilometers) off Nigeria's Bakassi Peninsula, along Nigeria's southeastern Atlantic Ocean coastline, near the border with Cameroon.
"The group boarded
the tanker from two fast boats and took control over the vessel and
locked the crew in the mess room" before heading for the Niger Delta,
the Bulgarian-based Maritime News reported.
The
ultimatum from the separatists was given at the weekend by "General
Ben." Ben is not a separatist but "some Niger Delta militants have shown
interest in working with us," said Uchena Madu, a leader of the
Movement for the Actualization of a Sovereign State of Biafra.
The
hijacking — the first such act claimed by the separatists — indicates
they could be working with some Niger Delta oil militants blamed for
recent bombings of pipelines in the oil-rich south, escalating conflict
in a country already burdened by Boko Haram's deadly Islamic uprising in
the northeast and violent ethno-religious confrontations between
farmers and herders in central Nigeria. Africa's biggest economy and oil
producer also is battered by slashed petroleum prices.
Secret
police on Oct. 17 detained Nnamdi Kanu, director of banned Radio
Biafra, and since have accused him of terrorism, sparking protests in
which police are accused of killing several demonstrators.
Nigeria's
Igbo people prosecuted a civil war to create a separate state of Biafra
in the southeast that killed a million people in the 1960s. Many Igbos
charge they still suffer discrimination.
In
an apparently unrelated development, pirates seized the Greek-owned
chemical tanker MV Leon Dias off Nigeria's coast, according to an
official of the Nigerian Maritime Administration and Safety Agency who
insisted on anonymity because he is not authorized to speak to
reporters. He said it was hijacked on Friday, other reports said Sunday,
and diverted to an oil terminal off Cotonou, capital of neighboring
Benin. Maritime News said the chief officer was seriously injured and is
being held hostage with four other seamen.
