Militia units under Libya’s National Transitional Council (NTC) have arrested Abdullah al-Senussi, the former intelligence chief of the Gaddafi regime.

Al-Senussi was captured near the town of Birak, in the southern desert close to where Gaddafi’s son, Saif al-Islam was captured on 19 November, the UK’s Guardian newspaper reports.

His arrest means all the leading figures of the former regime have now been killed, captured or driven from Libya.

Al-Senussi was called the “the executioner” of the Gaddafi regime by Luis Moreno Ocampo, prosecutor at the International Criminal Court (ICC), which has indicted him and Saif al-Islam.

The NTC says it will decide before December whether to hand over Saif al-Islam to the ICC for trial, or to try him in Libya.
