TRIPOLI (Reuters) - Two oil storage tanks remain on fire at Libya's Es Sider oil port while two others have collapsed almost a week after clashes there sparked the blaze, a spokesman for state National Oil Corp (NOC) said on Tuesday.

Fires at two other storage tanks at Libya's biggest oil port had been extinguished but the damage was unclear, NOC spokesman Mohamed El Harari said.
