Some Brooklyn College students waved banners and raised their voices on campus Tuesday in protest of the Iraq war.

Dozens of students marked the four-year anniversary of the U.S.-led invasion. War critics say they don't support a war that's entering its fifth year with no end in sight. They cite thousands of American troop deaths, several from Brooklyn, and countless Iraqi casualties.

Pro-war students also showed up at the demonstration, saying the United States should not pull out of the war-torn country until the job is finished.
