The pipeline, operated by the Nigeria Petroleum Development Company, was still in flames as of 7pm when our correspondent left Ughelli, the scene of the attack, for Warri on Tuesday.
Although security sources in the state confirmed the attack under the condition of anonymity, none of them could confirm the true cause of the incident.
They stressed that they were mobilising in collaboration with the Delta State Fire Service in the area to put out the inferno.
However, another military source dismissed the claim that militants were responsible for the attack, noting that indiscriminate bush burning was responsible for the inferno.
When contacted on the incident, the spokesperson for the Joint Task Force code-named Operation Delta Safe, Lt. Col. Olaolu Daudu, could not immediately confirm the incident.
He promised to reach out to his men in the area and get back to our correspondent later.
Daudu, however, did not fulfill his promise as of the time of filing this report.
