Central Tunis has been rocked by suicide blasts a few times in recent years. The country has been struggling with the threat posed by militant groups active in remote areas bordering Algeria ever since the toppling of President Zine Abidine Ben Ali in 2011.

In late October 2018, a female suicide bomber blew herself up near the Municipal Theater on Habib Bourguiba Avenue, the main street of the capital.

Tunisia, which relies heavily on tourism, has beefed up its security measures since a series of attacks in 2015, including the attack on the museum of Bardo where 21 people were killed, and another attack in the resort of Sousse, which killed 38 people.
