The mother of Nimisha Fathima, who is suspected to have joined terror outfit Islamic State in Syria, met National Commission for Women chairperson Rekha Sharma and requested her help in tracking down her daughter.

Bindhu handed over a formal complaint to Rekha Sharma with details of the incidents before and after Nimisha went missing and the messages she sent from Syria. She pointed out that there has been no information about the youth for the past one-and-a-half years.

"I don't know what happened to my daughter? I don't know where she is. I have raised my concerns with the women's commission," Bindhu told reporters after meeting the NCW chief. She had earlier sought a National Investigation Agency (NIA) probe into the conversion of her daughter and her disappearance.

Nimisha, a Thiruvananthapuram native, had left the country to join Islamic State around two years ago with her husband Isa, who is also a convert. She was pregnant at the time and later sent her mother a message saying she has given birth.

The youngster was a final year dental student in Kasaragod when she got married to a Christian youth named Bexen, who later converted to Islam along with Nimisha, his brother Bestin and his wife Merin. They are among the 21-odd people who went missing from Kerala and believed to have joined the ISIS in Syria. 

Meanwhile, Rekha Sharma will meet state police chief Lokanath Behera in Thiruvananthapuram on Wednesday. The NCW chief is in Kerala seeking more details in connection with the Hadiya case, which is under consideration of the Supreme Court.
