No ability to delete files on sftp mounted by sshfs

I mounted sftp dir via sshfs like: cat | sshfs -o password_stdin,allow_other,default_permissions,uid=0,gid=0 $USER@$HOSTNAME: $MOUNT_DIR -oauto_cache,reconnect And the problem is that I can't delete files on $MOUNT_DIR, despite they have full permission and root as owner, e.g.: -rwxrwxrwx 1 root root 10505331 Aug 22 14:50 some_file.zip Wondering if it's at all not available when mounting sftp or it's related with the flags used on sshfs.
