In our teens, we dreamed of making peace in the Middle East. Then my friend was shot

At a summer camp for kids from conflict zones, I met my brave, funny friend Aseel. He was Palestinian. I was Israeli. When he was killed by police, my hope for our future died with him

On 11 May 2021, I was sitting with a small group in a cafe in southern Tel Aviv, studying Arabic. Our teacher, a Palestinian citizen of Israel, had been telling us that he and his pregnant Jewish wife kept getting turned down by landlords who would not rent their property to a mixed" couple. We were almost at the end of the three-hour class when air raid sirens sounded. A few days earlier, missiles had been launched from Gaza into Israel, but this was the first time they had hit Tel Aviv. Beyond the fear of an airstrike, I had a sad, heavy feeling. I had recently returned to live in Israel after 15 years studying and working abroad. I remembered a time, in the mid-1990s, when I had believed that Israel was going to be different, more just and less violent. That belief now felt like a distant memory.

My faith in Israel's future had been inspired by an experience I shared as a teenager with a group of extraordinary people. As we waited for the rocket fire to stop, I recalled one of those people in vivid detail, a person I have barely been able to talk about in my home country for more than 20 years. His name was Aseel Aslih.
