"What the judge said I listened, but I am not going to be disheartened by it and will take my fight to higher courts," Jafri, who broke down after the judge pronounced his verdict, told reporters.
Zakia's husband Ehsan Jafri was among 68 people massacred during the Gulbarg society riots.
"We are disappointed but not disheartened. We will appeal against this judgement in higher court," Teesta Setalvad of NGO Citizens for Peace and Justice, who has been supporting Jafri in her quest for justice, said.
"Somebody asked me, if this is a big relief for Modi, to which I would say that this relief will continue for just 20 days till we file a case in higher court," Desai said.
"We can now appeal to a sessions court, then to high court and then the matter can go to Supreme court. But once we get the judgement we will decide where to appeal," Desai said.
