China has urged Brazil to ensure there is no repeat of an incident in which a man threw an explosive device at its consulate general in Rio de Janeiro. The device damaged the premises but no one was injured in Thursday evening’s attack, the consulate said in a statement. Qu Yuhui, a minister counsellor from the Chinese embassy in Brasília, has raised the issue with the Brazilian foreign ministry. “Minister Counsellor Qu severely condemns this violent incident and is communicating with Brazilian authorities, urging them to investigate the case immediately, and hopes they will adopt measures to prevent the occurrence of similar attacks,” a statement from the embassy said.

Surveillance footage showed a man, wearing a hat and a face mask and dressed in a black coat, walking towards the Rio consulate. He then took out an explosive from his pocket and paused for about 10 seconds before throwing the bomb towards the gate of the consulate. He fled the site after the attack. Local police collected the remains of the explosive and are searching for the suspect based on the surveillance record, Chinese state broadcaster CCTV reported.
