UNITED STATES - United States President Barack Obama will address Muslim unrest related to an anti-Islamic video and underscore his commitment to preventing Iran from acquiring a nuclear weapon in his speech to the United Nations this week, the White House said on Monday.
"I would expect the president to address the recent unrest in the Muslim world and the broader context of the democratic transitions of the Arab world," said Press Secretary Jay Carney about the speech scheduled for Tuesday.
"The United Nations General Assembly presents another opportunity for him to underscore that Iran must not be allowed to develop a nuclear weapon," Carney added.
Meanwhile, Muslims protested in Nigeria, Iran, Greece and Turkey on Sunday to show anti-Western anger against a film and cartoons insulting Islam had not dissipated by Sunday.
As delegates from around the world gathered in New York for a UN General Assembly where the clash between free speech and blasphemy is bound to be raised, US flags were once again burning in parts of the Muslim world.
Iranian students chanted "Death to America" and "Death to Israel" outside the French embassy in Tehran in protest at the decision by satirical magazine Charlie Hebdo to publish cartoons of the Prophet Muhammad, days after widespread protests - some deadly - against a film made in the United States.
Shi'ite Muslims in the Nigerian town of Katsina burned US, French and Israeli flags and a religious leader called for protests to continue until the makers of the film and cartoons are punished.
In Pakistan, where fifteen people were killed in protests on Friday, a government minister has offered $100,000 to anyone who kills the maker of the short, amateurish video, The Innocence of Muslims.
Calls have increased for a UN measure outlawing insults to Islam and blasphemy in general.
In Athens, some protesters hurled bottles of water, stones and shoes at police who responded with teargas.
Calm returned when demonstrators interrupted the protest to pray.
Hours later, dozens of Muslim inmates in Athens' main prison set mattresses and bed sheets on fire in protest.
Firemen with four engines battled the flames in some cells but police and government officials said late at night the situation was under control.
