Authorities in Pakistan are searching the Arabian Sea after a cargo plane registered in Pakistan goes missing off the country’s coast. Multiple outlets report the aircraft is a Boeing cargo plane carrying five crew members. According to flight and early reports, the plane loses contact with air traffic control shortly after reporting a navigational system problem, and it rapidly descends before contact is lost. Pakistan’s airports authority says search and rescue operations are underway, and the Pakistani navy and civilian teams use planes and ships to look for the aircraft. The search is focused on waters near the presumed crash area off the Karachi coast. Several reports state that Prime Minister Shehbaz Sharif directs authorities to speed up rescue efforts. In addition, The Independent and Stuff.co.nz report that wreckage is found within about 12 hours of searching, though details about how it is confirmed to be from the missing plane are not provided in the summaries. Officials continue to locate the aircraft and assess what happened to the five crew members.
