Twin suicide bomb attack in Tunisia kills one, injures several others

Tunisia's capital was hit by two suicide bombings today, leaving at least one person dead and several others injured.

The Tunisian Interior ministry says one police officer has died from his injuries after a suicide bomber targeted a police patrol in a busy commercial street in central Tunis, where the first blast occurred.

The bomber targeted a police patrol on the main thoroughfare of Charles De Gaulle Avenue, according to an Interior Ministry statement.

It injured three civilians and several security personnel, who received "received varying degrees of injuries."

That attack took place nearly simultaneously with another at the government's anti-terrorism brigade headquarters on the outskirts of Tunis.

"One person blew themselves up behind the back door of the police department in El Gorjani neighbourhood," the statement said.

At least four security personnel were injured in the El Gorjani bombing -- two of them seriously, according to Interior Ministry spokesman Sofien Zaak.

An employee at the nearby French Embassy told CNN he saw a police car that appeared to have been damaged by the first blast but gave no further details on the origin of the explosion. He added that he did not see any injured people.

The first bombing was at 10:50am local time and the second was at 11am local time.

The attack came a day after the fourth anniversary of the Sousse attack, in which gunman went on a rampage on a Tunisian seaside resort, killing 38 people.

A state of emergency has been in effect for Tunisia since the terror attacks.

Tunisia has been struck repeatedly by terror attacks. In October a female suicide bomber struck the city centre, killing only herself.
