Libyan rebels say navy attack on tanker would be 'declaration of war'
Abb-Rabbo al-Barassi, self-declared prime minister of the movement, warned Libya's navy not to "harm" the tanker docked at Es Sider, according to a statement.
"Such a move would be a declaration of war," said the statement, sent to Reuters by a spokesman.
