Yusuf was just an infant when his father was killed by a US drone. Shortly afterwards Yusuf's maternal uncle arrived from ENgland, where he had been living for the past 20 years and fearing the same fate may await Yusuf and his mother, helped them relocate to London. Yusuf's mother made sure that Yusuf stayed faithful and dedicated to their religion as Yusufs father had been a very devout person. As he grew older he began to be influenced by more radical imams and slowly became radicalised himself.
Several months before the outbreak he was told by his imam that he would be going back to Takistan under the pretence that he wanted to learn more about his culture and its traditions, but in reality they was being sent to attend a training camp run by self proclaimed Mujahideen fighters who were looking for recruits to carry out attacks in England to send a message to those they viewed as sympathisers of the USA and enemies of Islam.
After months of training a group of about 15 people were to travel back to London to start planning and carrying out attacks. They were all to take different routes back in an effort to avoid any suspicion and so just days before the outbreak, Yusuf was sent into Chernarus where he was to holiday for a wreek before flying to Turkey for another week and then back to London. Due to the outbreak he was unable to leave Chernarus.
