Indian/Pakistani/South Asian Drama with young Orphan Girl

This movie was a drama about a young girl who I think was an orphan who was trafficked through several locations (nothing sexual, she was just moved from building to building.) She ends up in an apartment with a woman and her son that’s around the same age where she stays for a bit and isn’t treated badly, but isn’t treated as well as the son. In the end we find out her purpose was to be a suicide bomber when the woman puts a backpack bomb on her and leads her to a busy street and leaves her there… then it ends. The entire movie was not in english.
