A 7.9-magnitude earthquake jolted Nepal and parts of northern India on Saturday, killing more than 4,300 people and injuring thousands more. It is the most destructive earthquake that Nepal has suffered since 1934. Several countries have offered relief, most notably China and India. The rival nations, which together surround Nepal, have made an effort to woo the stricken nation even as they eye each other from their own borders.
