LONDON—Oil prices jumped more than $3 on Monday, with Brent crude climbing above $111 a barrel, as European Union nations considered joining the United States in a Russian oil embargo and after a weekend attack on Saudi oil facilities.
Brent crude futures were up $3.40, or 3.2 percent, at $111.33 a barrel by 0958 GMT, adding to a 1.2 percent rise last Friday.
