Pro-Gadhafi forces have launched fresh attacks on the rebel-held city of Misrata, shelling it from three sides, according to Libyan rebel spokesperson Hassan al-Misrati who spoke to Reuters on Wednesday. Twelve rebel fighters have been killed and thousands of pro-Gadhafi troops are trying to enter the city, al Misrati said. The attack is the most intense effort by pro-Gadhafi forces to take the city after heavy bombardment waned in mid-May. Meanwhile, NATO has also intensified its bombing campaign in the North African country, announcing in Brussels that “real progress” has been made. NATO Secretary General Anders Fogh Rasmussen said the international community should start preparing for a post-Gadhafi era in Libya.
