AMMAN, Jordan -- Scores of Jordanian protesters demanding democratic reforms from their king have denounced what they say is years of U.S. interference in the region's politics and have burned an American flag.

About 300 protesters chanted, "America is the head of the snake," as the flag burned at the protest in the capital, Amman. Most of the activists were from leftist and nationalist parties.

They also demanded Prime Minister Marouf al-Bakhit step down and called for press freedom in response to police attacks on journalists and activists during a protest last week.

Jordan's King Abdullah II is a staunch U.S. ally. He has responded to months of protests with a pledge to consider allowing voters to choose the prime minister and the Cabinet. Currently they are appointed by the king.
