A tanker loaded illegally with crude from a rebel-held port and intercepted by the U.S. Navy arrived Sunday off Tripoli and its crew were detained, Libyan maritime and official sources said.

The secretary to the Tunisian ambassador in Libya has been kidnapped, the foreign ministry in Tunis said on Saturday.

According to an embassy source, the incident occurred on Friday when the kidnappers forced Mohamed bin Sheikh into their vehicle, which had stopped his car in the Ain Zara suburb of eastern Tripoli.

The U.S. Navy handed over to Libyan authorities Saturday an oil tanker it boarded after the vessel took to sea with crude illegally loaded at a rebel-held port, the American embassy said.

A car bomb Monday targeting a military academy in Libya's restive eastern city of Benghazi killed at least seven soldiers and wounded 12, military and hospital sources said.

Benghazi, cradle of the 2011 uprising that toppled veteran Libyan dictator Moammar Gadhafi, has seen near-daily attacks on security and other targets in recent months as the weak Tripoli government struggles to rein in former rebel brigades turned militias.

U.S. Navy Seals boarded and took control of an oil tanker Monday that had loaded crude at a rebel-held port in eastern Libya and escaped to sea, the Pentagon said.

The weak Tripoli government's failure to halt the tanker had plunged the country into one of its biggest crises since Moammar Gadhafi was toppled by a NATO-backed uprising in 2011, with parliament ousting Prime Minister Ali Zeidan, who fled the country.
