The two explosions rocked the city center within 30 minutes of each other, according to police and a journalist at the scene of one of the blasts.
One blast went off near the Central Police Station and another near Parliament. The cause of the explosions was not immediately clear and no group has claimed responsibility.
The first explosion occurred at about 10 a.m. local time on Kampala’s Buganda Road, according to the journalist at the scene.
Dr. Rose Byanyima, the Deputy Executive Director at the Mulago National Referral Hospital, told CNN the hospital has received 27 people with multiple injuries from the blast at the Central Police Station.
She said that all of the patients were police officers — seven women and 20 men — and that 19 people were in critical condition.
Traffic in Kampala has been severely restricted following the explosions, with authorities urging public to close businesses and leave the area.
Police and army personnel cordoned off streets around the blast site and several ambulances were deployed.
Images on social media showed several people lying on the streets near the entrance of Central Police Station and Kampala’s High Court.
At Parliamentary Avenue, where the second explosion occurred, all streets have been cordoned off by security, with legislators and parliamentary staff evacuated.
