By Joseph Erunke ABUJA-Some Igbo elders have called on relevant authorities to deal decisively with members of the Indigenous People of Biafra (IPOB), saying the current level of force being deployed may not be enough to curb their violent excesses. According to the elders, decisive force was required at this time, considering recent events, which suggest that IPOB was determined to undermine security and peace in the South East, which is an integral part of the country. To buttress their point, the Igbo elders drew attention to the attack on security operatives within the Orlu council of Imo State, warning that the proscribed group may likely carry out more daring attacks, unless urgent action was taken deter them.
