The four staff members of the International Criminal Court (ICC) detained in Libya returned to The Hague, an ICC spokesman said on Tuesday.
"They are reunited with their families now," ICC spokesman Fadi El Abdallah told Xinhua.
"They are in a good condition, both in spirit as in health. For the time they really need to be with their families."
The four staff members, Alexander Khodakov from Russia, Esteban Peralta Losilla from Spain, Melinda Taylor from Australia and Helene Assaf from Lebanon had been detained by a local Libyan militia since June 7.
They went to Zintan to meet Saif al-Islam Gaddafi, the captured son of the late Libyan leader Muammar Gaddafi.
According to the ICC the four detained staff members were "well treated."
On Monday the four were released and they flew back from Tripoli to the Netherlands together with Judge Sang-Hyun Song, President of the ICC. (Xinhua/NAN)
