Brasilia, Brazil ? Authorities said Sunday there were no survivors among the 155 people aboard the Brazilian jetliner that crashed deep in the Amazon jungle, as rescue workers began to pull bodies out of the twisted wreckage.

The Boeing 737-800 apparently clipped a smaller executive jet midair Friday, crashing in jungle so dense that crews had to cut down trees Saturday to clear a space for rescue helicopters to land. The smaller plane – carrying Americans – safely landed at a nearby air force base.

The Brazilian air force said in a statement that rescue workers had combed through the wreckage and found no signs that anyone could have survived the crash.

The list of passengers on the commercial jet was not released, and it wasn’t clear whether any foreigners were aboard.
