  • Markets supported by a drop in available crude inventories"Prices ... rallied on the back of noticeable de-stocking of crude inventories"

and Reuters also discuss the situation I Nigeria as being a factor boosting price:

  • rebels in Nigeria threatened to attack the country's petroleum infrastructure
  • Traders said prices had been pushed up after reports that Nigeria's militant group Niger Delta Avengers threatened to launch attacks on the country's oil sector in the next few days
