Suspected attacks by Yemen's Houthi rebels targeted two ships in the Red Sea on Monday, authorities said, near where crews hope to salvage a tanker loaded with oil and still ablaze after another assault by the group.

The attacks are believed to be the latest in the Iranian-backed rebels' campaign that has disrupted the $1 trillion in goods that pass through the Red Sea each year over the Israel-Hamas war in the Gaza Strip as well as halted some aid shipments to conflict-ravaged Sudan and Yemen.
