Colonel Gaddafi's son Saif al-Islam has been captured, Libyan officials say.

利比亚官员称，卡扎菲之子赛义夫已被抓捕。

He was taken by fighters near the southern town of Obari and flown to the city of Zintan in the north. Saif al-Islam told a journalist he was well.

He is the last key Gaddafi family member to be seized or killed. Libya's new prime minister says he will get a fair trial in Libya.

Saif al-Islam, 39, is wanted by the International Criminal Court (ICC) for alleged¹ crimes against humanity.

A militia²（民兵组织，自卫队） force allied³ to the ruling National Transitional Council (NTC) said he had been captured in the desert about 50km (30 miles) west of Obari, and taken to their base in Zintan in the north.

A commander of the Zintan militia, Wisam Dughaly, said Saif al-Islam had been captured along with several aides as they tried to smuggle⁴ him out to neighbouring Niger.

Fighters said they were taken without a shot being fired.

"At the beginning he was very scared. He thought we would kill him," one of his captors, named as Ahmed Ammar, told Reuters news agency.

Libyan TV showed pictures of Saif al-Islam on the plane to Zintan with bandages（绷带） on his left hand.

Asked by Reuters reporter Marie-Louise Gumuchian during the flight if he was feeling all right, he said simply: "Yes." He added that he had been injured in a Nato air strike a month ago.

Interim⁵ Prime Minister Abdurrahim al-Keib told reporters in Zintan: "We assure Libyans and the world that Saif al-Islam will receive a fair trial."

He added that he was happy for him to remain in Zintan rather than be transferred to the capital, Tripoli.

"Our brothers and sisters here and the authorities are definitely trustworthy. We trust their ability to be able take care of this person," Mr Keib said.

The Zintan fighters, who make up one of the powerful militia factions⁶ in the country, have said they plan to keep Saif al-Islam until they could hand him over to Tripoli.

Information Minister Mahmoud Shammam said Gaddafi's son would face justice in Libya itself.

ICC spokesman Fadi el-Abdallah told the BBC that Libya had a legal obligation to hand Saif al-Islam over to the court, and that the final decision on a trial venue⁷（地点） was up to ICC judges after consultations⁸ with Tripoli.

ICC prosecutor⁹ Luis Moreno Ocampo said he was travelling to Libya for talks on the issue, adding: "The news is Saif will get justice. Where and how, that we will discuss."

The European Union urged Libyan authorities to ensure that Said al-Islam is brought to justice in full co-operation with the ICC.

British Prime Minister David Cameron called on the country's leaders to ensure he was tried "in line with international standards".
