Kahina Ziri was a Nairomian citizen who falsely testified against Superman after the incident in Nairomi, having been hired and blackmailed by Lex Luthor. Though Kahina managed to reveal the truth to Senator Finch, she was ultimately silenced and killed by Anatoli Knyazev, making her true testimony too late, as Finch would also get murdered shortly thereafter.
At some point before the Nairomi incident, Lex Luthor would hire and blackmail Kahina Ziri into testifying against the world's beloved hero Superman, with Lex having Kahina memorize a deceitful script.

The incident of Superman's involvement in Nairomi generates quite a bit of controversy throughout the world (as Knyazev and his men had successfully framed Superman for the deaths of many), with Senator Finch and her committee (responsible for studying Superman) interviewing Kahina, who (reciting Lex Luthor's script) tells the Senate how her parents had been killed in the crossfire following Superman's involvement (in fact, both of them are very much alive). While Finch assures Kahina that the committee holds Superman responsible for what occurred in Nairomi, the actress pretends to take little solace from this, claiming that the US government would never be able to force Superman to answer to them, since he seemingly answers to no one, not even (as she speculates) to God.
A few days ago, Kahina is interviewed by a reporter on live news, where she states that had Superman been in her presence she would ask him how he decides: "which lives count, and which ones do not?" Clark, who watched this interview on TV, is visibly uncomfortable at the accusation.
Kahina's apartment in Gotham City is visited by Clark Kent shortly thereafter, as he wishes to confront and interview his accuser face to face. However, Kahina's neighbors reveal that Kahina left some time ago, due to her fear of being dealt with by Lex Luthor's minions (primarily Knyazev).
Revelation and DeathEdit
Weeks later, shortly before the hearing regarding Superman's involvement in Nairomi takes place, a very guilt-ridden Kahina travels to the US Capitol and manages to reveal the truth to Senator Finch, after which she promptly departs, passing by Lois Lane (who appears to recognize her) in the process.
Kahina seemingly disapproves of Superman, hence her agreement to play out a deceptive charade in front of the US Senate and on TV for Lex Luthor. However, she eventually regretted doing so, and confessed the truth to June Finch, though it would ultimately prove too late.
