May 13 (UPI) -- Israel expanded its attacks on Lebanon on Wednesday, carrying out a series of drone strikes on vehicles along the coastal highway south of Beirut and killing at least 12 people, including two children, the Lebanese Health Ministry said.

The escalation occurred a day before Lebanon and Israel were to begin a third round of U.S.-mediated talks in Washington on Thursday and Friday.

The Israeli drones targeted cars in three separate attacks on the coastal highway in the Jiyyeh, Saadiyat and Barja areas, some 12 miles south of Beirut, according to security sources.

The Health Ministry said eight people, including two children, were killed in the strikes, while four others died in similar attacks on their cars between the port city of Sidon and the border town of Naqoura farther south.
