Exhibition stands for Israeli weapons makers Israel Aerospace Industries (IAI) and Rafael Advanced Defense Systems were empty at the start of the opening day of the week-long Dubai Airshow, amid Israel’s bombardment of Gaza, Reuters reports.

It was not clear why the IAI and Rafael stands were empty. Neither company immediately responded to emailed requests for comment.

An exhibition stand for the locally registered company of Israeli firm Elbit Systems was staffed. One staff member declined to answer press questions.
