Pirates who hijacked a Russia-owned oil tanker bound for China carrying oil worth $52 million have warned against any rescue attempt and said the MV Moscow University was headed towards the Somali coast, Reuters reported. "Any attempt to rescue the ship will certainly endanger the crew. The ship will be docked at Garacad," a pirate called Abdi told Reuters. He said it was too early to talk about a ransom. Somali sea bandits have taken tens of millions of dollars in ransoms from hijacked vessels, with heavily laden oil tankers considered a particularly lucrative prize. -- SPA
