Terror and chaos in Kabul

The Times speculates that behind the targeted killings might be some factions in addition to the Taliban. It's not clear what factions might be in point, but it is pretty clear at this point the Taliban is behind such attacks. It's possible to assume that they carry out their attacks through their third-party criminal groups but what makes the difference? It's still Taliban carrying out these attacks against innocent civilians. The claim that magnetic bombs are homemade is also questionable, at least we should cast doubt on Afghan government officials who make such claims under anonymity. How does the Afghan government know that the sticky bombs are homemade? We know that every one of those bombs are exploded so far and the question is, how did the government find out about the nature of the bombs after they blasted? The degree and magnitude of explosion of all these magnet bombs reveal that they are not homemade, they are rather imported from one of the two neighboring countries.
