As we go to press, the key towns of Brega and Ajdabiya have now been taken by the rebels and Qaddafi forces are everywhere in retreat. Libyan rebel troops are surrounding Sirte, birthplace and symbolic heartland of the Qaddafi regime. Their siege positions in Misurata are also less under-threat than last week. The change of fortunes for the rebels is largely as a consequence of the international air strikes. And that action now seems to be directed at “regime change”. Germany, Italy and Turkey continue to argue for a softer option.
