MADRID — A 51-year-old German woman died Sunday from injuries suffered in the Aug. 17 terrorist attack in Barcelona, raising the overall death toll in Spain’s recent rampages by Muslim extremists to 16, health officials in Catalonia said.
The woman died in the intensive care unit of Barcelona’s Hospital del Mar, according to the regional health department.
The latest death raises the toll to 14 in the attack in Barcelona’s popular Las Ramblas boulevard. Another man was stabbed to death in a carjacking that night as the van driver made his getaway, and another woman died in an Aug. 18 vehicle-and-knife attack in the nearby coastal town of Cambrils.
More than 120 people were wounded in the attacks. Authorities say 24 remain hospitalized, five of them in critical condition.
On Saturday, an estimated 500,000 peace marchers flooded the heart of Barcelona, shouting ‘‘I’m not afraid,’’ a public rejection of exremist violence.
Emergency workers, taxis drivers, police, and ordinary citizens who helped immediately after the Las Ramblas attack led the march. They carried a street-wide banner with black capital letters reading ‘‘No Tinc Por,’’ which means ‘‘I’m not afraid’’ in the local Catalan language.
The phrase has grown from a spontaneous civic answer to violence into a slogan that Spain’s entire political class has unanimously embraced.
Spain’s central, regional, and local authorities tried to send an image of unity Saturday by walking behind the emergency workers, despite earlier criticism that national and regional authorities had not shared information about the attackers well enough with one another.
In a first for a Spanish monarch, King Felipe VI joined a public demonstration, walking in Barcelona along with Prime Minister Mariano Rajoy and other officials. A separate antiviolence rally was held in the northern town of Ripoll, home to many of the attackers.
In London on Sunday, police arrested a second man in connection with a suspect who drove up to a police van not far from Buckingham Palace, then reached for a 4-foot sword, an incident detectives called a terrorism attempt.
Scotland Yard said three officers were slightly injured when they confronted the 26-year-old man who drove at the police van then stopped in a restricted area outside the gates of Queen Elizabeth II’s London residence Friday night.
