Oil prices edge higher, with Brent crude near $105/barrel, after renewed strikes on Saudi Arabia's main airport and a fresh tanker attack near the Strait of Hormuz raise supply risk concerns. West Texas Intermediate traded around $92. King Khalid International Airport in Riyadh came under attack again Sunday by Iran-backed Houthi militants, a day after a strike killed 12 people. A drone hit a tanker near the Sohar anchorage off Oman, outside the strait, the same day.
