Police investigating the homicide of two men in a drive-by shooting in Kiryat Ata on Friday night say it was likely part of a gangland war. The men, in their 20s, were shot in their car from a passing vehicle, police said. One of the victims was known to the police. Officers recovered a stolen car in the area on Saturday morning, and are checking to see if it was used in the shooting. In a separate incident near Ben Shemen, police suspect a man murdered his ex-wife before committing suicide on Saturday. An investigation was launched by police after the bodies of Yafa Rehavi of Ariel, and her ex-husband, Shlomo Rehavi, were found. Yafa Rehavi had been reported missing since Friday. The couple reportedly have seven children. A search of the man's car uncovered a suicide letter and a handgun, police said. The couple had been separated for six months, and the man had expressed an intention to reconcile with his ex-wife in a second letter found by police. Meanwhile, a series of stabbings, robberies, and assaults - some fueled by alcohol - were reported in Gush Dan over the weekend. Police arrested one suspect and were searching for two others after a 25-year-old man walking his dog in Tel Aviv was assaulted by three men, believed to be intoxicated, on Friday night. The men attacked the dog, and stabbed the man with a broken bottle after he tried to defend his pet. He was lightly wounded. In Ramat Gan, a man smoking a cigarette was confronted by two suspects who claimed to be upset that he was smoking on Shabbat. An argument ensued, and the man's 29-year-old friend was stabbed with a knife. He was taken to hospital and released after receiving treatment. In Tel Aviv, a 40-year-old man was forced to hand over hundreds of shekels in cash by a group of men. He was not injured. Also in Tel Aviv, a 22 year-old man was carjacked at knife point after stopping at a bakery. Police are searching for a number of suspects. Elsewhere in the city, the mother of an 18-year-old youth called for an ambulance after she found her son in bed with stab wounds. After sustaining the injuries on Friday night, the youth returned home rather than seek medical attention. He is recovering from moderate wounds at the Assaf Harofeh Medical Center in Tzrifin.
