The last time Mohammed Yousaf talked to his son, Sajid Yousaf, on 8 June, the son was waiting anxiously in Libya for smugglers to pack him and hundreds of others on to a boat bound for the other side of the Mediterranean.
Six days later, the overcrowded fishing trawler sank off the coast of Greece. Sajid, 28, a shopkeeper and father of two from the small town of Khuiratta in Pakistan-administered Kashmir, is among the hundreds missing, presumed dead.
