CANBERRA, Australia — U.S. seabed exploration company Ocean Infinity says it has offered to take the financial risk of a renewed search for the missing Malaysian airliner, as victims’ families urge the Malaysian government to agree to a private-sector hunt for Flight 370’s wreckage. Malaysia, Australia and China suspended a nearly three-year search in the southern Indian Ocean in January after failing to find any trace of Malaysia Airlines Flight 370. Ocean Infinity said in a statement on Friday it remained hopeful that Malaysia would accept its offer to continue the search. A support group for victims’ families, Voice370, said under the terms of the offer made in April, Ocean Infinity “would like to be paid a reward if and only if it finds the main debris field.”
