The families of three teenagers who are believed to be making their way to Syria spoke with the media at New Scotland Yard and made direct appeals to the girls to come home on Sunday, 22 February.
Abase Hussen said his 15-year-old daughter Amira Abase, told him she was going to a wedding on the morning she travelled to Gatwick Airport to fly to Turkey, and had been behaving in a normal way. He said: "She said 'daddy, I'm in a hurry', there was no sign to suspect her at all."
Mr Hussen said the family had asked her about a fellow pupil at Bethnal Green Academy in east London who fled to Syria in December. She said: "I'm sad for that little girl."
"It's completely different now," Mr Hussen said. "We are depressed, and it's very stressful. The message we have for Amira is to get back home. We miss you. We cannot stop crying. Please think twice. Don't go to Syria."
He added: "What she's doing is completely nonsense. Remember how we love you. Your sister and brother cannot stop crying," and that his wife has a "broken heart."
Speaking of her younger sister, Shamima, Renu Begum, 27 said: "Mum needs you more than anything in the world. You're our baby. We just want you home. We want you safe."
She added: "Her family love her more than anybody else in this world can. If anyone is telling her they're going to love her more than us, they're wrong. We're hoping she wouldn't do anything that would put her in danger."
Sister of Kadiza, Halima Khanom said: We want you know that we all miss you and we love you. Everyone is hurting because we don't know if you are safe, especially mum. Find the courage in your heart to contact us and let us know you are okay, that is all we ask."
Officers from the MPS Counter Terrorism Command continue to work with authorities in Turkey to trace the whereabouts of the girls.
