A US official close to President Barack Obama and Secretary of State John Kerry said both men are disturbed over what is being perceived in their inner circle as "Jewish activism in Congress" that they think is being encouraged by the Israeli government, Israel Radio reported on Thursday.

The official has informed Israeli government figures that the president and secretary of state are disappointed over repeated attacks made against them by leading members of the Jewish community in the US.

According to Israel Radio, Israeli diplomats and foreign officers have warned against this trend. According to officials based in foreign missions, the Israeli government is increasingly being viewed as fanning the flames among American Jews by encouraging them to promote the official government position while making no room for opposing viewpoints.
