Two people were killed and nine others were injured in the terror attack, with the finger of blame being pointed at pro-Russia forces though no definitive cause has yet been established.
"Latvia expresses its strong support for the peace process in Ukraine, including a sustainable political solution to the conflict in the east of Ukraine with respect for Ukraine's independence, sovereignty and territorial integrity," a statement by the Foreign Ministry said.
"Latvia categorically condemns terrorism and any violence against civilians."
Prime Minister Laimdota Straujuma was herself in Kyiv on Sunday, participating in events commemorating the Maidan along with the Presidents of Lithuania, Germany, Georgia and Poland and Prime ministers of Estonia and Slovakia.
They took part in a procession in honour of the 'EuroMaidan' and commemorated the dead victims by laying candles at the scene of the Maidan events.
Straujuma also held talks with Ukraine President Petro Poroshenko and Giorgi Margvelashvili, President of Georgia - both of whose countries have borne the brunt of Russian military aggression in recent years.
