Dela Rosa told reporters at a news conference in the southern Philippines city Saturday evening that authorities had eight witnesses, and a sketch of one suspect. Fifteen of the injured are in critical condition, CNN Philippines reported, citing Southern Philippines Medical Center director Leopoldo Vega. Davao City Vice Mayor Paolo Duterte -- the President's son -- said the city had received a bomb threat two days before the blast, CNN affiliate ABS-CBN reported. "But this is not the first time that Davao City has been sacrificed in the altar of violence." SWAT team members patrol the streets of Manila in the wake of the Davao City bombing.
