President Emmerson Mnangagwa escaped injury in an explosion at a political rally on Saturday and vowed the "cowardly act" would not derail Zimbabwe's first election since the ouster of former strongman Robert Mugabe.
Mnangagwa was unscathed and later pointed out he'd had numerous attempts on his life in the past, saying he was used to them by now.
This follows an explosion on the stage at White City Stadium just as the rally ended.
The president was in Bulawayo, Zimbabwe's second city and an opposition stronghold, to campaign for his Zanu-PF party ahead of nationwide elections taking place on 30 July.
"We have 25 people at Mpilo, 12 at Mater Dei and four at UBH, giving us a total of 41 who have so far approached our health institutions complaining of injuries", the minister told state media.
However three were seriously injured.

Mnangagwa adopted most of Mugabe's security and bureaucratic system, fearing a complete overhaul, which the military had sought, could cause government instability and cost him votes.
Also among the VIP injured list was Chiwenga's wife, Mary, cabinet minister Oppah Muchinguri- Kashiri and Zanu PF national commissar Englebert Rugeje.
He suggested he was the target of the attack, which he said also injured vice president Kemo Mohadi.
The President himself has openly joked about the attempts, including during his campaigning. Six times my office has been broken into; cyanide was put in my offices so many times.
"The people of Bulawayo, I love them and they love me; it's people outside Bulawayo I can assure you".
Mthwakazi Republic Party spokesperson Mbonisi Gumbo said Zanu PF must stop dragging Bulawayo residents into its violence. We pray for the speedy recovery of all the injured and call for the security forces to get to the bottom of this atrocious incident. The strongest response to violence is peace.
"In November, we all came together motivated by a dream, (for) a free, democratic and prosperous Zimbabwe, a peaceful Zimbabwe", he said in an audio clip.
