Israel Greenpeace activists scale the Calavatra (String) bridge in Jerusalem to send a message to President Barack Obama to stop Arctic drilling.

The protest comes as President Obama visits Israel and Palestine, and just one week after the publication of a damning report by US authorities of a series of failures that characterized Shell’s attempts to drill for oil in the fragile Arctic waters off Alaska last summer.

Greenpeace is urging President Obama and Secretary of State John Kerry, delegate to the Arctic Council, 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.
