President Barack Obama urged Israel on Thursday to open its borders with Gaza.

The plea came in a speech that signalled the new US administration’s shift from Bush-era policy on the Middle East and the world as a whole. In a high-profile address on his second day in office, just hours after he signed an executive order to close the centre at Guantánamo Bay, Mr Obama proclaimed that the US would “actively and aggressively seek a lasting peace between Israel and the Palestinians” in the wake of this month’s Gaza war.
