A source who pleaded for anonymity said that several patrol vehicles belonging to the security operatives were set ablaze by gunmen.
The Spokesman of the command, SP Nnamdi Omoni, who confirmed the attack in a statement in Port Harcourt on Sunday, said details of the attacks were still sketchy.
Omoni, however, did not disclose the number of casualties in the attacks.
He said: “I can confirm the attack on security personnel along the Omagwa/Isiokpo/Elele – Owerri Road, and details are sketchy.
“Meanwhile, the area is now calm with reinforced and increased joint patrols on the stretch of the road and other areas in the state by security agencies.
“So far, the state is calm and secure, and no cause for alarm,” Omoni stated.
NAN further gathered that the checkpoints attacked by gunmen included checkpoints manned by the Joint Military Task Force (JTF) and Nigeria Customs Service (NCS) located between Elele, Isiokpo and Omagwa communities in Rivers. (NAN)
