A massive explosion ripped through a busy cafe in the Moroccan city of Marrakesh on Thursday, killing at least 15 people and wounding as many as 20 others.
The Argana restaurant on Jamaa el-Fnaa square is popular with tourists and 10 foreigners have been confirmed dead.
Authorities suspect a suicide bombing after nails were found in one of the dead bodies.
If proved to be the work of Islamic militants, it would be Morocco’s biggest terrorist attack since suicide bombings killed 45 people in Casablanca eight years ago.
One eyewitness told Moroccan state television that he noticed a bad smell, “like gas or gunpowder”. “There was then a big blast like those you see in the movies,” he said.
The iconic Jamaa el-Fnaa square is a favourite amongst foreign visitors and is listed as a UNESCO World Heritage site.
It is better known for its snake charmers, street performers and story tellers.
Morocco’s tourist industry has seen a drop in visitor numbers since popular uprisings across North Africa and the Arab world began earlier this year.
Officials fear this attack could further deter foreigners from visiting the country.
