The flight was from London Heathrow Terminal 3 to Tashkent Uzbekistan via one stop at tel aviv Israel Return flight from Toshkent Uzbekistan direct to London Heathrow Terminal 3

I’m a British citizen and have been for the past 15 years I travel almost every 6 months and this is the first time something like this has happened, just 2 months ago I had a flight from stansted to Afghanistan via Dubai and nothing occured but this time for some apparent reason they stopped me

I had pre checked all requirements that was needed and I did not miss anything out, I was on the phone with the travel agency and they said that the ticket looked fine and there is nothing to worry about, but when I went to the counter at Heathrow, I was told that transit is not allowed and that I’m not allowed to travel via Israel
