A Police CCTV footage shows a terrorist carrying a huge bag walking near CPS exploding and killing scores of pedestrians.
The CPS explosion occurred a few minutes after another huge explosion happened at Parliamentary avenue a few meters, in the city center.
The number of people killed in the twin attacks is yet to be known as Police is yet to address the public.
Tens have been injured and rushed to Mulago National Referral Hospital and Kampala Capital City Authority hospital.
All roads into the city have been temporarily closed and now ambulances are dominating the traffic in the city as they rush casualties to Mulago. Journalists who cover Parliament have been turned away, a clear indication that there will be no Parliament sitting today.
The blasts come a couple of weeks since a homemade bomb went off at a pub in the Komamboga suburb of Kampala killing one and injuring several, and another blast on a bus killed the suspected bomber.
The immediate previous two blasts were attributed to the rebel Allied Democratic Forces ADF. Government has vowed to stamp out the ADF, which has been conducting terror activities for about 25 years, and whose supreme leader Jamil Mukulu is in custody.
