Philippine police safely detonated an improvised bomb Monday morning near the U.S. Embassy in Manila, with a section of the road where it was found closed off.

According to the Manila Police District Information Office, the explosive was found in a rubbish bin at around 7:30 a.m. along the southbound lane of the Roxas Boulevard in Manila, a few hundred meters away from the embassy's compound.

The device, which was described as being made of an 81-mm mortar round, a cellular phone component and some wires, was detonated around 8 a.m., with the flow of traffic resuming around 30 minutes later once the area was cleared.

At a press conference in the afternoon, national police chief Ronald dela Rosa said that the improvised bomb bore a resemblance to one used in Davao on Sept. 2.

"According to our bomb data center, it's the same signature," dela Rosa said, adding that its design, construction and composition is the same as that which was used in the previous bombing incident.

Dela Rosa added that the improvised bomb had a kill radius of about 100 meters.

The September bombing incident happened at a night market in President Rodrigo Duterte's hometown of Davao, killing 15 people and injuring more than 60 others.

A state of national emergency was declared by Duterte after the bombing, a proclamation indicating an intensified campaign by the military and the police to suppress crime.

Three people were arrested almost a month later, with the suspects identified by the police and the military as members of the Maute group, a local terrorist organization seeking ties with the Islamic State group.
