U.S. crude oil futures ended lower for a second straight session on Thursday, after some disappointing economic data from the U.S. amid the geopolitical tensions in the Middle East and worries about the impact of Hurricane Joaquin.

The storm is expected to batter the East Coast over the weekend, threatening the Carolinas and Virginia. Hurricane Joaquin has strengthened to a Category 4 storm Thursday, slamming into a part of Bahamas. However, reports indicate uncertainty as to whether and when the hurricane will make landfall on the U.S. East Coast.

Meanwhile, in the Middle East, Russia has launched a series of air strikes targeting rebels in Syria for a second day, sparking worries of a wider conflict. As well, Iran officially announced its support for the Russian military campaign in Syria with the foreign ministry saying Moscow is “fighting terrorism” there.
