Oil prices fell during Asian trading hours on Tuesday as investors appear to shrug-off geopolitical tensions in the Middle East. The global benchmark, Brent crude, dropped 1.4 percent to $67.94 a barrel and the US WTI crude was down 1.3 percent to $62.46 a barrel. On Sunday, President Trump threatened to impose sanctions on Iraq and a bill of billions of dollars if the US are forced to leave the country after the Iraqi parliament voted to expel US troops. Trump also threatened to attack several sites in Iran if the country retaliates over the Iranian general Soleimani killing. Meanwhile, Iran announced it will abandon the 2015 nuclear deal limits.
