The Nigeria-based terror group Boko Haram is issuing a new threat against the neighboring country of Niger after it pledged to send troops to help fight the Islamic extremists.

In a translation published by the SITE Intelligence Group on Monday, the group said its fighters were prepared to carry out suicide bombings.

Over the last 10 days, Boko Haram fighters have repeatedly struck the town of Diffa but there have been no attacks on the capital of Niamey.

The new threat comes as officials from Niger and other neighboring countries meet in the capital of Cameroon to plot a joint military offensive against Boko Haram.

The terror group has fought a five-year insurgency against Nigeria's government but began stepping up its attacks against neighboring Cameroon, Niger and Chad this year.
