The crew of a UAE-owned suezmax detained in Egypt for six months has revealed what they call "mental and physical torture" onboard the vessel.

In an email to TradeWinds, the seafarers from the 163,000-dwt Sea Shark (built 1991) said the ship was held by Egyptian naval forces on 17 December.

Fuel has now run out on board and the vessel is using emergency generators, he wrote.
