Warplanes from Libya's official government attacked a ship off the Libyan port of Sirte on Sunday, the air force commander said.
"Our jets warned an un-flagged ship off Sirte city, but it ignored the warning," Saqer al-Joroushi told Reuters. "We gave it a chance to evaluate the situation, then our fighting jets attacked the ship because it was unloading fighters and weapons," he added.
An oil official said the ship was actually a tanker which had been carrying 25,000 tons of gasoil.
