The families of three British girls who've traveled to Syria have told lawmakers at Westminster they had no idea the teenagers were being radicalised.
They've also spoken of their anger at not being informed directly by London police that a friend of the three girls was already in Syria.
It comes as British Foreign Secretary Philip Hammond accused so-called 'apologists' in Britain of sharing responsibility for acts of terror carried out by jihadists and terrorists.

15 year-old Shamima Begum is one of three teenagers who traveled to Syria last month - thought to now be staying at an Islamic State controlled address.
Her sister Sahima told MPs the family had no idea she was being radicalised.
And further, that if police had told them a friend of Shamima's had gone missing, they would have acted.

Police gave a letter about the girls' friend to the girls - it never made it to their families, who think police should now make a full apology.
But Prime Minister David Cameron, talking to LBC, insisted the police can't take all the blame.

It comes as Phillip Hammond delivered a major speech to praise British security services in response to claims their actions have helped to radicalise people like Mohammed Emwazi - a young Londoner now known worldwide as Jihadi John.

And Calum Jeffray of the Royal United Services Institute has some sympathy with Philip Hammond's message - and the security services.

In terms of the three girls who traveled to Syria - their families told MPs they didn't know how they found the money to pay for their air fares to Turkey in cash.
Police say they believe they raised the funds by stealing family jewellery.
