WASHINGTON (CNN) - President Obama called Saturday for the Iranian government to refrain from violence and injustice against its own citizens.
"The Iranian government must understand that the world is watching," Obama said in a White House statement. "We mourn each and every innocent life that is lost. We call on the Iranian government to stop all violent and unjust actions against its own people."
He said the United States stands with all who seek to exercise what he called the universal rights to assembly and free speech.
The statement came as Iranian security forces cracked down Saturday on demonstrators in Tehran in continuing protests against the outcome of Iran's June 12 election.
