Pakistan Navy search and rescue teams battled rough seas Thursday as the search for the five-member crew of a cargo plane that crashed into the Arabian Sea entered its second day, officials said. Wreckage was recovered Wednesday, with no sign of the missing crew members. This was reported by Qazaqyia.kz citing Associated Press.

The aircraft, operated by private carrier K2 Airways, reported a malfunction in its navigation system before losing radio and radar contact late Tuesday, according to the Pakistan Airports Authority.

Since then, ships and aircraft have continued to comb waters nearly 300 kilometers (180 miles) southwest of Karachi, where the plane disappeared from radar while approaching Pakistan's largest city from Sharjah in the United Arab Emirates.

The cause of the crash remains under investigation.

Two officials familiar with the ongoing search and rescue operations told The Associated Press that the aircraft's main fuselage and the five crew members remain missing. They spoke on condition of anonymity because they were not authorized to speak to the media on the record.
