Terrorist group Boko Haram has left a letter at the scene of the explosion that killed over 50 people on a market day at Sabon Gari, threatening Borno residents to join the group or die.
Local vigilante has stated that threat letters cautioned the locals to wake up and join force with the terrorists to fight 'Holy War' against 'infidels' or face more attacks.
Wakil Modu has stated that, the warning letter supposedly written in 'Hausa' by the insurgents advised the people that, fighting the cause of Allah is a holy business, which all who believe must wake up to join in the blessing of henceforth.
The vigilante added that they have reported several times for action to be taken principally at Talala and Ajigil area of Damboa local government area, where it was considered to house Boko Haram members, but nothing was being done about it.
He said: “Last week a Fulani man brought a report, which stated that he saw a Boko Haram member with sophisticated weapons and a tanker. When he told us we went and reported but nothing happened. The attack on the market, we got a hint, but the market is an open place people can sneak in. We are still calling on government to do something because this is the third time the market is being attacked although this is the worst attacked so far.”
