Greenpeace activists scale the Calatrava (String) bridge in Jerusalem and unfurl a 150square meter banner reading Obama: stop arctic drilling. The message is to US President Barak Obama who is currently visiting Jerusalem, to stop oil exploration in the arctic. The protest comes as Barack Obama enters the second day of his visit to Israel, and just one week after the publication of a damning report by US authorities into the catalog of failures that characterized Shells attempts to drill for oil in the fragile Arctic waters off Alaska last summer. Greenpeace is urging President Obama to seize this opportunity and ban all offshore oil drilling off the northern coast of the US, because the risks of a spill in these icy waters would be catastrophic.
