El Al airplanes are seen on the runway at Ben Gurion International airport near Tel Aviv, in this file picture taken August 22, 2011. Israeli media reported on Monday that pro-Palestinian hackers had threatened on January 15, 2012, to bring down the websites of the Tel Aviv bourse and El Al. The site of the Tel Aviv Stock Exchange (TASE) was disrupted on January 16, 2012, and the El Al Israel Airlines website also crashed but officials at Israel's flag carrier would not confirm or deny the incident was the work of hackers.
