Oil prices rose in choppy trading on Tuesday as efforts to strengthen sanctions on Iran and unrest in the region hiked the geopolitical fear premium and offset worries about global economic growth. "It's Iran sanctions, Egypt and Syria and even Libya today, putting the fear premium into prices, especially ahead of the (US Thanksgiving) holiday," said Dominick Chirichella, senior partner, Energy Management Institute in New York.
The United States, Britain and Canada on Monday announced new sanctions on Iran's energy and financial sectors to put more pressure on Tehran to abandon what the UN's International Atomic Energy Agency said were attempts to use its nuclear program develop weapons.

Turkey called on Syrian President Bashar al-Assad to step down, tightening regional pressure on Damascus after Arab states threatened sanctions over Syria's crackdown on unrest.
