President Viktor Yanukovych arrived Saturday in eastern Ukraine after it was rocked by an unclaimed series of blasts that injured at least 26 ahead of the Euro 2012 football tournament.
"The president will visit victims of the explosions in the city's hospitals," his press service said in a statement.
Yanukovych was also set to chair a meeting of the coordinating committee that is overseeing the investigation on the ground.
The security service is heading the investigation into the blasts, after prosecutors on Friday opened a probe into a suspected "terrorist act."
Four explosions went off in a busy area of central Dnipropetrovsk on Friday, wounding at least 26 people. On Saturday, 22 of the injured remained in hospital, although officials said none was in a life-threatening condition.
The Ukrainian security service on Saturday appealed for "citizens who have any information on the circumstances of the explosions and the people involved in the crime" to call specially set-up hotlines.
The first bomb, hidden in a rubbish bin, exploded shortly before noon Friday, followed by three more blasts over the next hour, all in the same busy part of the city on the Dniepr River in eastern Ukraine.
Yanukovych has called the attacks a challenge to the nation ahead of its high-profile role as co-host with Poland of the Euro 2012 football tournament, which starts June 8.
Europe's football governing body UEFA has said it is confident Ukraine will be able to ensure security despite the attacks, although Donald Tusk, prime minister of co-host Poland, said: "This issue needs to be treated with the utmost seriousness."
Leading some to suspect a political motive, Dnipropetrovsk is the home town of Yanukovych's arch-foe, 2004 Orange Revolution leader Yulia Tymoshenko, who is serving a disputed jail term that has strained Ukraine's ties with the European Union.
