It's believed over 200 have been injured
Thousands of demonstrators stormed official buildings, demanding political reform after Tuesday’s explosion which killed more than 150 people.
The Prime Minister has offered early parliamentary elections, but the government has rejected calls for an international investigation into the blast.
Around 300,000 people are unable to return home after buildings, doors and windows were damaged by the shockwave.
Officials believe it could cost upwards of 12 billion euro to repair the damage to the city.
