The We Grounded and Nabia music festivals, which recently kicked off in the Sinai Peninsula in northern Egypt, provoked an uproar across the country as they were organized by Israelis and coincided with Egypt’s anniversary of the Sinai liberation.

The two festivals in Sinai were organized in mid-April, 350 kilometers (217 miles) from Tel Aviv, on the occasion of the Jewish Passover holiday. But the timing coincided with Egypt’s commemoration of the liberation of Sinai, which was occupied by Israel from 1967 until April 25, 1982.

According to the official website of the Nabia Festival, the event ran from April 17 to April 20 and tickets were sold at 900 Israeli shekels ($279). The festival management referred the Israelis who planned to attend the festival to the Saladin Hotel, which, according to the website of the festival, is a 10-minute walk from the festival square. According to the site, an all-inclusive package at the hotel cost 1,700 shekels ($527).

The We Grounded festival, whose website refers attendants to the Hilton Nuweiba Club Resort and Time Coral, runs from April 20 to April 23.
