By Staff of Al Jazeera - Thousands of demonstrators have taken to the streets of the Philippine capital of Manila to denounce President Rodrigo Duterte's war on drugs, as they marked the death anniversary of one of the country's pro-democracy heroes. Human rights advocates, youth groups, and religious communities on Monday defied a tropical storm that brought steady rain to gather at the memorial of the 1986 people power revolution to call for an end to the killings in Duterte's war on drugs. Amid public pressure, Duterte said on Monday there could have been abuses in his anti-drug war policy. "There is a possibility that in some of police incidents there could be abuses. I admit that," Duterte told reporters in Manila. "These abusive police officers are destroying the credibility of the government." Al Jazeera's Jamela Alindogan, reporting from Manila, said at least 4,000 people joined in the rally, adding that a separate protest was also held in another part of the city. Protesters are demanding an independent investigation into the summary executions and police operations that left thousands of people dead. They said the president should be held accountable for the deaths. Demonstrators waved Philippine flags and carried banners that read: "Resist the Fascist!", "Stop the Killings!", and "We will fight" among others.
