As the hours and days passed the seriousness of my colleagues' arrest began to dawn and my guilt grew and grew. On that day in September I was at the African Union conference in Cairo where the African Foreign Ministers were meeting to discuss the possibility of US air strikes on Syria. I had crossed live to the studio in the blazing heat with updates all day when we heard police were in our offices and were taking equipment away. We decided to keep reporting - if we were on air we should be safe was my thinking. But as we sat in on the AU council session in the grand debating hall our satellite engineers, who were camped outside in the satellite truck, took a call from their boss. 'The police are headed your way. They're going to arrest anyone working for Al Jazeera,' they were told. 'Get out!' So they and my cameraman left in a hurry.
