The war crimes trial against former Congolese militia leader Thomas Lubanga is "prejudicial", his lawyer has told day two of the case at The Hague.

She claimed the prosecution's use of anonymous witnesses and secrecy clauses for the International Criminal Court (ICC) trial would hamper the defence.

Mr Lubanga, 48, denies using hundreds of child soldiers in DR Congo's five-year conflict, which ended in 2003.
