Redirect all pages to new domain

This code in .htaccess does redirect all requests to a new domain:

RewriteEngine On
RewriteRule ^(.*)$ http://WWW.NEW-DOMAIN.COM/ [R=301]

The problem was, all other directives work like: 

www.old-domain.com/bla -> www.new-domain.com/bla

but I need


www.old-domain.com/bla -> www.new-domain.com

www.old-domain.com/more/bla -> www.new-domain.com

So the htaccess code above works fine.
