Eight persons were killed, including the parents and four children of a single family, when two cars were involved in a head-on collision on the Adham to Qalwa road in Al-Leith on Saturday. The Yemeni driver of the other vehicle and his Saudi passenger also died in the incident. Among the dead were a three-month-old boy and a two-year-old girl. The incident prompted locals to renew calls for permanent patrols of the region's highways which they say have seen an abundance of accidents, often caused by stray camels and cows. No official reason was given for Saturday's accident.
