Poor kids though; a little over a month ago they were living a fairly normal British life, and now they're stuck in a Pakistani orphanage (let's be honest, that's what it is) with a murdered sister and parents who have off to save their own skin.
Even assuming they have the language skills to communicate their needs, there's no guarantee that they will have their needs met.
I hope they are returned to the UK, but it's unclear if extended family members will be willing and deemed suitable to look after them via a kinship care arrangement, and in the event that they go into foster care the chances are that they will be split up - good luck finding a foster carer with five spare bedrooms.
None of the options are great for the kids right now, it's just that some are less *advertiser censored* than others.
