How to get an arbitrary number of GET parameters via MOD_REWRITE?

Question

Apache HTTP Server

There are links like:
www.site.ru/city123
www.site.ru/city123/type54/project1198
www.site.ru/project1198/type54/
In other words, the number of parameters may be arbitrary, or may not be at all.
Here is a code that helps to isolate only the first pair of letters + numbers

RewriteRule ^([a-z]*)([0-9]*)/*$ index.php?$1=$2%{QUERY_STRING}

At the output, I have: How in this case to get all GET parameters, if their number can be arbitrary or not at all?
$_GET[city] => 123
