Despite the fact that the southern African country had been exposed to some form of political violence in the past, Zimbabweans were not used to an environment that was as "charged" as that experienced over the weekend.
"The UAE condemns this cowardly act of terror, which seeks to undermine security and stability of Zimbabwe by resorting to violence", said a statement issued by the Ministry of Foreign Affairs and International Cooperation, on Saturday.
Zimbabwe President Emmerson Mnangagwa announces the date for the general elections in Harare, Zimbabwe, May 30, 2018. It was reported that several people had been injured but the extent of the injuries had not yet been established.
Since taking over after Mugabe resigned last November, Mnangagwa has been preaching peace and re-engaging Western powers.
Meanwhile, ZBC reporter Reuben Barwe, who interviewed Mnangagwa after the incident, has come under fire for asking him whether he suspected the people of Bulawayo to have been behind the attack.

Dramatic footage shows the moment a bomb went off just inches from Zimbabwe's president at a campaign rally.
"The President's response has been: We answer with love".
"Investigations are underway", presidential spokesman George Charamba told the state-controlled Herald newspaper. Mugabe has said he felt betrayed by Mnangagwa, a former protege, and has called his presidency illegal.
Chiwenga said everyone must continue to campaign peacefully as Zimbabwe wants to register an election which is free, violence-free and credible. "So it might be possible that those who were put in place may not have received good security training or they may have less security experience", said Matyszak.
Mnangagwa told the Zimbabwean Broadcasting Corporation that this was not the first attack on his life and that there had been previous attempts to poison him.
Without mentioning names, Mnangagwa said there were some people who did not accept his presidency and his "usual enemies" were behind the blast.
