On Twitter, Ai hasn’t shared many words either, mostly posting links to articles about Murtaja, once adding the words “So sick.” He also retweeted a post from a follower who wrote: “They... terrorize the Palestinians. #Gaza is an open air concentration camp.”In May 2016, Ai arrived in Israel to film for the documentary – his first visit to the region. He was initially denied an entry permit to Gaza before it was eventually granted. He filmed there and around Israel for the documentary, and also met at the Israel Museum with then-director James Snyder. The next year, an exhibit of Ai’s work, “Maybe, Maybe Not,” opened at the museum and closed just last month. Ai returned to Israel for its opening in June 2017, where he told reporters, “My voice should be heard,” according to Agence France-Presse. “I have to make the argument... [and not say] ‘OK, let’s boycott it, and it’s nothing to do with me.’ I think that’s too easy.”
