Ugandan forces are part of an African Union peacekeeping force in Somalia fighting al-Shabab, an insurgent group allied to al-Qaeda.
Last month, the Islamic State group said it was behind an attack on a bar in Kampala which killed a 20-year-old waitress.
Proceedings in parliament have been called off and MPs advised not to come to the building following Tuesday's blasts.
Cars parked near parliament went up in flames while the explosion near the police station shattered windows, senior police officer Edward Ochom told AFP news agency.
"What we can say [is] this was an attack but who is responsible is a matter that is under investigation," he added.
Health ministry spokesman Ainebyoona Emmanuel said that of those being treated in hospital, four were in a critical condition.
2 explosions rock Kampala. Earlier, some bystanders complained about the delayed response by the Police. First responders included Red Cross personel who were using fire extinguishers to curb the fire on Parliamentary avenue. #NTVNews
