The Oct. 28 deadly incident in Tiananmen Square—in which an SUV ploughed into the crowd, leaving five dead and nearly 40 injured—appears to have been an act of terrorism. Police are reportedly checking hotels and vehicles for two men said to be ethnic Uighurs. It is unclear if the two suspects survived the crash or are thought to be accomplices. Accounts also do not make clear if the car's occupants were all killed in the crash; Reuters called the incident a "suicide attack," but also implied the attackers set the SUV on fire after driving it into the tourist-packed square. The Uighur ethnicity of the suspects has not been officially confirmed, but is based on surnames provided in police notes left with hotel management in the city to assist in the dragnet. Radio Free Asia cites reports from locals that police are checking ID cards of Uighurs on Beijing's streets and instructed hotels not to accept patrons from Xinjiang.

At least 13 inmates were killed and some 30 injured in a clash between rival gangs Oct. 10 at Pedrinhas prison in São Luis, in Brazil's northeastern state of Maranhão. Authorities said violence broke out after guards discovered inmates digging an escape tunnel. The inmates fought the attacking guards and started a fire, as members of rival gangs took advantage of the confusion to settle scores. Then, as news of the conflagration broke, relatives of inmates gathered outside the prison, demanding information. When this was not forthcoming, they began to throw stones at the guards, took over a roadway, and set several buses on fire.

At least three are dead in clashes as opposition parties attempt to enforce a three-day general strike in Bangladesh, aimed at bringing down the government. All public gatherings have been banned in the main cities of Dhaka and Chittagong, but protesters have repeatedly defied the decree, leading to street-fighting with police and government supporters. The opposition Bangladesh Nationalist Party (BNP) and Jamaat-e-Islam are demanding Prime Minister Sheikh Hasina install a caretaker administration to oversee the January general election. Hasina, who heads the ruling Awami League, rejects the demand. Tensions have been growing for months between the secular but increasingly authoritarian Awami League and a radicalizing Islamist opposition.
