Explosions at Riyadh airport halt flights as oil prices surge

Several explosions were heard in Saudi Arabia's capital on Thursday, including one at Riyadh airport that halted flights, while Brent crude jumped about 5% to around $105 a barrel.

The incidents coincided with a rise in U.S. Treasury yields, which hovered near 5.35% on Thursday, and the U.S. dollar strengthening against the yen and euro.
