Spain's interior minister is meeting with representatives of almost all political parties to brief them about the investigation into the deadly attacks that killed 15 people in Catalonia last week.
It was the first time the anti-terror group has met since the deadly attacks in the French city of Nice last year. The governing Popular Party and the main opposition Socialists set up the group in 2015.
Lawmakers of all other parliamentary parties are attending the meeting in Madrid, either as participants or as observers, except for a coalition of Basque nationalist parties who have criticized the government's anti-terrorism policies.
Interior Minister Juan Ignacio Zoido was expected to explain the decision to not upgrade the country's terrorism alert level after the attacks in Barcelona and a nearby coastal town.
