(CNN) Once again, nature has dealt a deadly blow to Haiti.

At least 12 people were killed and 188 were wounded after a magnitude 5.9 earthquake struck northern Haiti on Saturday night, the country's interior ministry said Sunday.

On Sunday, President Jovenel Moïse visited the coastal city of Port-de-Paix, just 11 miles (18 kilometers) from the quake's epicenter.

"I will make sure the proper state systems are fully mobilized to help the victims," Moïse tweeted.

Je suis sur place, dans les zones touchées par le séisme, afin d'apporter de l'aide à la population. Le PM est également sur les lieux pour superviser les équipes de secours et coordonner leurs actions. Je félicite cet élan de solidarité et de soutien de la part des citoyens. pic.twitter.com/KCjG6FLdBc — Président Jovenel Moïse (@moisejovenel) October 7, 2018
