I spent some time in Oman and Kuwait this year and in Egypt a few years back and found the people to be extremely welcoming and lovely. When I look around York I see many people from other parts of the world - the Middle East included, who appear to be living peaceful and productive lives.
From my perspective, you would be welcome to come here, or write from Egypt and publish here as an author. There are no restrictions in terms of political embargos in place between the UK and Egypt, and certainly no cultural obstacles.
Both on my blog and in 'real life' I have many friends in just about every part of the world, including the Middle East, and can truthfully say that their stories are as interesting as any I've found in the English speaking world. In fact, the unique (for me) perspective of writers who produce stories stemming from cultures other than my own (here in England) lends them a special cachet.
Providing your written English is of a good standard (and I can see from your question that it is) and your stories are interesting and entertaining, there are no obstacles to a literary agent from a England agreeing to work with you.
Good luck with your writing.
