Tunisia's Interior Ministry says authorities have found the body of a member of the National Guard who was kidnapped by militants in the northwest of the country.

Ministry spokesman Mohammed Ali Aroui told the state news agency that the body was found Monday in the northwest El Kef province without its head.

The man was stopped by militants Sunday night while he was driving with his brother in this rugged region near the Algerian border that has been the scene of terrorist activity in the past. His brother was released, said Aroui.

Aroui added that major operations were planned to catch the perpetrators.

The regions along Algeria's border have been the scene of several attacks on security services by militants.
