You could change your <meta http-equiv=refresh content=60>
to <meta http-equiv=refresh content=300>
to change the refresh interval to 5 minutes.
And/or, you could install a .htaccess to block them from your site entirely like <FilesMatch "(.*)">
Order Allow,Deny
Allow from all
Deny from xxx.xxx.xxx.xxx
</FilesMatch>
replacing the xxx.xxx.xxx.xxx with the full (or partial) IP address of the Algerian accesses.
