An Etihad Airways flight from Dublin to Abu Dhabi was diverted to Al Minhad military base in Dubai yesterday following a "security threat onboard".

"The crew completed all necessary in-flight checks as per procedure, with no abnormalities found, then followed the authorities' instructions to undergo further security checks at the air base," said Etihad in a statement.

The guests, baggage and aircraft crews went through additional security screening which took several hours, Etihad said.

The majority of transferring guests were re-booked on flights this morning and were offered overnight accommodation in Abu Dhabi.

Etihad Airways has apologised for the inconvenience caused and added that "the safety and security of our guests and crew is our top priority".
