GORANI: Well, there is a manhunt that continues in Belgium for two suspects who escaped after a furious shootout with police. Investigators combed the Brussels apartment where gunmen on Tuesday opened fired on officers who arrived thinking that the apartment was empty. They recovered a Kalashnikov rifle, an ISIS flag, ammunition and a book about radical Islam. A police sniper killed one gunman a 35-year-old Algerian. But as Nema Elbagir shows us the two suspects who escaped is raising questions about how prepared the police really were here.</s>NEMA ELBAGIR, CNN CORRESPONDENT: It was through this window that a police sniper managed to neutralize one of the two men holding offices in (inaudible) with Kalashnikovs. It was only once they entered the premises that they realized that two of the men that they were searching for had managed to escape. And you can see coming round the back of the building how easy it was. You can see more broken windows and what is presumed to be the suspect's escape route. As the manhunt continues of course so, too, does the fear and the information as residents not just here but all over the Belgian capital struggle to come to terms with exactly what is happening again in their midst.</s>UNIDENTIFIED FEMALE: Working with different kinds of hard equipment from 3:00 until 6:00 in the night.</s>ELBAGIR: What is clear is that Belgian police were unprepared for what unfolded here at this premises. They were, as they describe it, carrying out an ongoing manhunt only to find themselves caught in a fire fight. This will only of course increase the scrutiny on Belgium's handling of its terror threat and the impact that that has and is having not just here in Belgium but across Europe.
