A deep-sea search for Malaysia Airlines Flight 370, which vanished over 12 years ago with 239 people, has resumed in the Indian Ocean. The search is being conducted by US-based marine robotics firm Ocean Infinity under a 'no-find, no-fee' agreement. Using advanced underwater drones, the company aims to locate the Boeing 777 wreckage in targeted areas believed to have the highest probability of success, offering hope for closure to affected families.
