May 4 (Reuters) - The United Arab Emirates said its air defences were engaging missile and drone threats on Monday evening as firefighters battled a blaze at a major oil industry zone following a drone attack which authorities said had originated from Iran.
The Gulf Arab state's foreign ministry said in a statement that the attacks marked a serious escalation and posed a direct threat to the country's security, adding that the UAE reserved its "full and legitimate right" to respond.
