Search efforts for the missing Malaysia Airlines Boeing 777 deep in the southern Indian Ocean were derailed on Thursday by adverse weather conditions, even as new satellite images provided fresh leads of debris possibly linked to the aircraft.

Thailand’s space agency said on Thursday it had spotted as many as 300 objects in a part of the southern Indian Ocean where the aircraft was last identified by satellite signals — the biggest lead yet in the search for the Boeing.

The objects were scattered in an area stretching over 450 square km, around 2,500 km southwest of Australia.

Search efforts have been hampered by poor visibility, high winds and icing, and had to be suspended midway on Thursday.

The Australian Maritime Safety Authority (AMSA) said search operations covered 78,000 square km.
