Sister of Syria girl: 'We would have questioned her'

Families of the three schoolgirls missing in Syria have complained that they never saw a letter from police, about how a friend of the girls had gone to Syria in 2014.

Sahima Begum, sister of Shamima Begum, said police should have ensured that the letter reached the girls' families.

She said her family would have questioned her, if they had received the letter, which highlighted the risk of their radicalisation.
