Qatar’s Interior Ministry said 13 children were among 19 people killed in a fire that broke out in one of the country’s fanciest shopping malls late Monday morning, raising questions about building safety in the booming Gulf state.

At least some of the victims died as rescuers struggled to reach a child care center at the Villaggio mall in the capital Doha, according to Qatar’s Minister of State for Interior Affairs, Sheik Abdullah bin Nasser Al Thani.

Four of the children killed were Spanish citizens living in the small Arab emirate, the Spanish Foreign Ministry said. It did not identify the children, citing Spanish privacy regulations.

Also, a 3-year-old French child was among the victims, the deputy minister for overseas French citizens, Yamina Benguigui, said in a statement.

Young New Zealand triplets were also believed to be among the victims, said New Zealand’s Prime Minister John Key, though he could not yet confirm the deaths.

“We tried our best, but when we got there, the children were trapped inside. We are very sorry for what happened. We tried as much as we could to save these people,’’ Sheik Abdullah told reporters in Doha.

Four teachers and two civil defense officials were among the dead, the Qatari ministry said on its official Twitter page.

Another 17 people were injured, including four children, according to authorities. Most of those hurt were rescuers responding to the blaze.

Witnesses earlier reported thick black smoke pouring from the ritzy mall around midday. Amateur photos and videos posted online showed firefighters rescuing victims by climbing on the roof.

The Interior Ministry said the fire was extinguished hours later.

The cause of the fire is under investigation.

Thick smoke and heat hindered rescue efforts, as did a lack of floor plans and malfunctioning sprinkler systems, the ministry said on Twitter.

Sheik Abdullah said all buildings in the country abide by safety requirements, but a special committee will nonetheless be set up to monitor building safety standards.

The Villaggio opened in 2006 and is one of Qatar’s most popular shopping and amusement destinations. Retailers include many well-known Western brands, such as Foot Locker, Pizza Hut, Starbucks and British department store Marks & Spencer, according to the mall’s website.

Malls throughout the oil-rich Arab Gulf are popular with families looking for entertainment destinations that provide relief from soaring summer temperatures. The Villaggio includes an ice skating rink, theme park, movie theater and indoor Venice-style gondola rides.

New construction projects such as the Villaggio have transformed the face of once-sleepy Doha in recent years, as the country benefits from a hydrocarbon boom. The OPEC member state is the world’s largest exporter of liquefied natural gas.
