Last November, I wrote of waiting for the grey ticks to double up and go blue when sending WhatsApp messages to my friend Ghassan Abu Sittah, who in October had narrowly missed being killed in the bombing of al-Ahli Arab and al-Shifa Hospitals in Gaza, where he had travelled from London to work as a surgeon. He survived and was inaugurated as the rector of Glasgow University, with 80 per cent of the student vote, on 11 April. He has set up a fund for Palestinian children, planning ‘for the day after’, and is speaking tirelessly to the media and audiences across the world.
