It's been months since Boko Haram leader, Abubakar Shekau, pledged allegiance to Islamic State (IS), early in March, ever since critics have questioned where the Islamist sect leader has been.
The unusual quietness from the vociferous Shekau have made security officials to speculate whether the group doesn't have the luxury of issuing threats.
One military source told PRNigeria that since the Army final push against the insurgents in the middle of February and order to clear all the boko haram camps before May 29 handover date, the Nigerian troops have been on the lookout for Shekau and other commanders of the sect.
“The guy simply disappeared from the radar and suddenly vanished. We wish we can catch him alive,” the source added.
The last time the world heard from Shekau was when he pledged allegiance to the Islamic State (IS), early in March which was posted on Boko Haram's Twitter account.
In that broadcast, he also vowed to disrupt the rescheduled elections.
Shekau was quoted to have said: “This election will not be held even if we are dead. Even if we are not alive Allah will never allow you to do it.”
He made these threats in Hausa language.
The threats by Shekau to disrupt the 2015 general elections did not hold water, as polls were conducted reasonably peacefully throughout the country on March 28 and April 11.
Nigerian troops have flushed out boko haram terrorists from the 21 local government areas that they occupied in three states of Adamawa, Borno and Yobe since the federal government asked for a six week extension to the date of 2015 general elections in February.
The military had attacked the notorious Sambisa forest which is believed to be the hideout of the Boko Haram terrorists.
On Wednesday, April 22, 2015, the Nigerian Defence Headquarters issued a statement informing the nation on the defeat of a top terrorists’ commander, Abu Mojahid, in the outskirt of Alagarno.
