Please help me find Karim, my brother from Iraq

My brother, Karim, and I were separated during the conflict in Mosul in 2009. I have spent every moment since trying to find them. We were crammed into an overcrowded boat crossing the Mediterranean. Karim was with us until the very last moment before the collapse of the building next to ours. I remember Karim as someone who loved to cook traditional dishes for everyone. I cherish the memory of teaching me to ride a bicycle in the backyard. We lost all communication in 2016. We heard a rumor they had been resettled in United Kingdom, but nothing concrete. Karim would now be approximately 37 years old. I would recognize them anywhere — compact build, thick eyebrows, always well-groomed. The not knowing is worse than any bad news could be. If anyone has information about Karim, I beg you to contact us. We have registered with every tracing service we could find.
