A Libyan officer was killed in a car bombing in the eastern city of Benghazi Wednesday three days after a colleague died in the same way.

"Officer Abusif al-Mabruk succumbed to his wounds" several hours after the blast, Al-Jala hospital spokeswoman Fadia al-Barghathi told AFP.

A security spokesman, Abdullah Zaidi, said the 44-year-old army intelligence officer had been gravely wounded when a device attached to his car exploded in the city's Al-Berka district.

On Sunday, another military intelligence officer named as Suleiman al-Fissi, was killed when a bomb placed under his car went off.
The explosion also seriously wounded his wife and two children.

Benghazi, cradle of the 2011 uprising that toppled dictator Moammar Gaddafi, has been rocked by a wave of attacks targeting police and army officers.

Also on Wednesday, army Colonel Issam al-Houidi was wounded in a murder attempt near Derna east of Benghazi, the official LANA news agency reported, adding his life was not in danger.
