The U.S. Senate on Monday rejected four measures restricting gun sales after last week's massacre in an Orlando nightclub, dealing a bitter setback to advocates who have failed to get even modest gun curbs through Congress despite repeated mass shootings.

A group of senators was still hoping to forge a compromise for later in the week aimed at keeping firearms away from people on terrorism watch lists, although that effort faced an uphill battle with critics in both parties sceptical about its chances.
