deleting rows with composite primary key

Is there a different syntax to the mysql delete statement when the "WHERE"
clause points only to half of the primary key?

The structure is as follows:
CREATE TABLE IF NOT EXISTS ` table1` (
  `id1` int(10) unsigned NOT NULL,
  `id2` int(10) unsigned NOT NULL,
  PRIMARY KEY  (`id1`,`id2`),
  KEY `id2` (`id2`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Query is
$query = "DELETE * FROM table1 WHERE id1 = '$recID';";

Error is a 1064 syntax error.

Any help is appreciated.
