Members of the centre-left US Democratic Party say they will keep fighting for gun control after the end of a 16-hour sit-in on the floor of the US House of Representatives.

"I crossed a bridge, it didn't take us one time. It took us three times," he said, drawing an analogy to repeated efforts to stage a march across a bridge near Selma, Mississippi that led to violent clashes in the 1960s and became symbolic of the fight for voting rights in the United States.
Centre-right Republicans, who control the House, forced the chamber to go into recess after holding a vote that passed along party lines shortly before 3 am (0700 GMT).
