Two Spanish tourists emerged unscathed from a Tunisian museum Thursday morning alongside the museum worker who helped hide them, one day after gunmen opened fire on visitors in an attack that left at least 23 people dead.

The Spanish Minister of Foreign Affairs Jose Manuel Garcia-Margallo confirmed to reporters in Spain on Thursday that the two tourists, Juan Carlos Sanchez and Cristina Rubio, were safe, according to the Associated Press. Rubio is four months pregnant.

At least 23 people were killed, including the two gunmen, and dozens were injured on Wednesday in the assault on the National Bardo Museum, the worst terror attack in the country in years.

The museum employee helped hide the two tourists in an office during the attack, AFP reports, citing a representative of the Tunisian security forces. All three people, who were uninjured, were taken to a hospital Thursday for medical tests.

“I thought my son was dead. Now I’m relieved,” the employee’s mother told AFP.

It’s still unclear how the three survivors were not found by security forces who spent the night searching for them following the attack.
