A small plane smuggling more than a tonne of cocaine from Colombia crashed in southeastern Mexico, killing two people on board and leaving police their biggest haul of the drug so far this year, the attorney general's office said on Friday Mexican military and police aircraft were tailing the drug flight when they lost radar contact with it on Wednesday night. It probably crashed due to bad weather, the office said in a statement. On Thursday, authorities found the crashed plane, a twin-engine turboprop, in the state of Quintana Roo with two bodies inside, one of them carrying a Colombian identification. Colombia is the No. 1 cocaine producer and much of its output is shipped through Mexico and ends up on U.S. streets. -- SP 2250 Local Time 1950 GMT
