The headquarters of the National Bank of Kuwait was engulfed by a huge fire today, sending 2,500 workers fleeing from the flames.

The blaze broke out in the bank's new skyscraper in Kuwait City at 11am local time, causing thick black smoke to pour into the sky.

The bank said there were no injuries but theKuwait Fire Service Directorate said six construction workers and one fireman were treated at the scene with minor burns.

It is not clear what caused the blaze which had been largely put out within hours.

The bank on Twitterdescribed the blaze as a 'partial fire' and said firefighters had extinguished 90 percent of it by 4pm local time (1pm UK time).

'NBK Management would like to thank the Kuwait Fire Department, the Ministry of Interior, the Emergency Medical Services for their quick response in extinguishing the fire at the new NBK Headquarter construction site and to the public on their concern for the safety of all,' the bank said in a tweet.

'More than 2,500 workers were evacuated from the site in record time without any injuries,' it added. (Daily Mail)
