Oil prices continued to rise on Sunday, adding to a 7 percent increase last week as the conflict between Israel and Iran deepens and threatens global oil supplies.
U.S. oil was last up 1,2 percent to $73,85 a barrel. Brent crude, the global index, rose 1 percent to $75 a barrel.
On Monday morning local time, explosions were seen in the coastal Israeli city of Haifa, damaging buildings and setting infrastructure ablaze after Israel said Iran had launched a new round of missiles.
Video from the attacks showed the missiles hitting the area around an oil refinery in Haifa.
The conflict has fueled fears about disruptions to oil exports from the region. Analysts have also raised concerns about a widening conflict that could affect the flow of oil through the Strait of Hormuz, the most critical chokepoint for oil supplies on the planet.
