The thirty people who were burnt to death and the five rescued alive were trapped in the vessel that caught fire at the Abuloma water front.
Our correspondent in Rivers says NEMA advance teams are moving to the Abuloma scene while fire fighters are battling that of Rumuokehi already.
Officials of NEMA's information department are asking for help from the fire service and multi-national companies around Abuloma for urgent assistance to battle that fire.
At Rumuokehi, a total of three tankers were seen still in flames while one had been successfully put out by men of the fire service.
A source told Daily Trust that the tankers were set ablaze by men of the JTF because they were being used by bunkerers.
Efforts are still being made to contact the JTF spokesman to get confirmation about their involvement.
However, FRSC's sector commander in Rivers state Kayode Olagunja said this about the Abuloma fire; " An oil vessel, around 9:45am, caught fire and exploded at the Abuloma water front, Trans Amadi in Port Harcourt.
"Fire is still restricted to the water area. FRSC, NEMA, Police and other rescue agencies are on ground. Casualty figures are yet unknown."
