Hundreds of protesters gathered in Barcelona, Spain, on Sunday denouncing Qatar’s support of terrorism, a report said.

The protesters, who included Spanish, French, Italian, Portuguese, German, Dutch, and British citizens, chanted against Doha rulers, holding them accountable for the Catalonian terror attack last month, reported Wam, the Emirates official news agency.

They accused Doha of killing dozens of innocent people in Spain and France through funding terrorist groups and extremists.

On August 17, Barcelona witnessed two deadly attacks; the first was in Barcelona while the other was in the coastal resort of Cambrils.

The two attacks led to the killing of at least 15 people and more than a hundred injured including citizens of 24 countries. The Spanish police reported killing five terrorists and arresting four suspects.

A report published by Spanish media earlier revealed that Qatari businessmen are financing and supporting terrorism in the province of Catalonia.

The protesters today called upon the Spanish government and other European countries to officially boycott their relations with the State of Qatar and not to cover up Doha's financing of terrorism under the cloak of investment.
