Heavy security in Guyana after unusual US warning

International flights are departing from Guyana under heavier than normal security following an unusual threat warning from the US Police and soldiers joined regular airport security at the main international airport in the South American country.
Transportation Minister Robeson Benn says authorities are conducting 100 percent security checks on passengers and luggage.
The first of three Caribbean Airlines flights departed for the US without incident today.
The US Embassy said on its website yesterday it had received "unconfirmed threat information" relating to Caribbean Airlines flights bound for the US. It advised US citizens to make alternate travel arrangements through Wednesday.

Guyana is hosting international visitors this week for an Islamic conference, but Ben said he did not know if there was a connection to the warning. The embassy declined comment.
