Saudi Arabia's ban of online functions on BlackBerry mobile phones is implemented.
Saudi Arabia, and subsequently the United Arab Emirates and Kuwait, urge all citizens currently in Lebanon to leave the country immediately. Recently, Saudi Arabia declared that a missile attack on its airport from Yemen was "an act of war" by Lebanon.
The United Arab Emirates will suspend some BlackBerry mobile services from October amid concerns that data from some equipment is being exported offshore and managed by foreign organisations. Saudi Arabia plans to suspend some services later this month.
