LEIDSCHENDAM, Netherlands -- The war crimes trial of former Liberian President Charles Taylor has finished hearing its final witness, a former rebel in Sierra Leone's civil war.

Sam Kolleh, an ex-member of the Revolutionary United Front rebel group, was the last of 21 witnesses to testify in Taylor's defense.

Kolleh insisted Taylor did not arm rebels in Sierra Leone, as prosecutors allege. He also claimed court officials tried to bribe and threaten him to testify that rebels gave Taylor diamonds.

Kolleh undermined his credibility by admitting lying during three different interviews with prosecution investigators.

Taylor is on trial at the Special Court for Sierra Leone on charges of arming and supporting notoriously brutal rebels in Sierra Leone's 12-year civil war. He denies wrongdoing.
