As a United States Navy plane circled overhead, two Philippine boats breached a Chinese coast guard blockade in a dangerous confrontation Tuesday in the disputed South China Sea to deliver food and other supplies to Filipino forces guarding a contested shoal.

Two Philippine coast guard vessels escorting the supply boats, however, were blocked by at least four Chinese coast guard ships for about five hours in the tense standoff near Second Thomas Shoal.
