Israel and GCC countries

"The warming of Israel's relationship with the Gulf States is not new. Until 2009 Israel had an interest office in Doha, Qatar, which was closed after Israel's operation in Gaza Strip. However, it's not a well-kept secret that Israel continues to have below the radar security and economic cooperation with the Gulf States. Israel's Budget Law of 2013 reveals the existence of an Israeli diplomatic office in an un-named location in the Persian Gulf between 2010 and 2012."
