The Australian defence force has apologised to a Bollywood actress for airing rumours she had sex with troops while touring a military base in Afghanistan.London-based Australian star Tania Zaetta is considering suing the defence department over the scandal, which centres on a morale-boosting tour she made to Australian military bases in Afghanistan last month. The defence department apologised to Zaetta late Thursday, expressing regret that a ministerial briefing note, known as a “hot issues paper”, detailing the rumours had named her and become public.
