Bombs wound 27 in Ukrainian city

KIEV (Reuters) - Four bombs exploded in a city in eastern Ukraine on Friday, wounding 27 people, including nine children, in what authorities described as an "act of terrorism".

President Viktor Yanukovich said the blasts in Dnipropetrovsk, six weeks before Ukraine plays host to the European soccer championship, represented "a challenge ... to the whole country."

Bomb attacks are a rare occurrence in the former Soviet republic and the blasts one after the other traumatised people in the city, one of Ukraine's main industrial centres with a population of around 1.3 million.

"I had just stepped out of my house when I saw people run down the street screaming 'Explosions!'," said 50-year-old local journalist Tetyana.

"There is panic in the city. People are taking their children out of schools and rushing to their homes," she said.

Police said the bombs had been left in rubbish bins at various points in the city. "No-one has been detained yet," a police spokesman said.

Authorities offered no immediate explanation of any motive or say who they thought could be responsible. But the prosecutor general's office formally opened a criminal case classifying the blasts as an "act of terrorism".

Dnipropetrovsk, 400 km (250 miles) southeast of the capital Kiev, is not one of the four Ukrainian cities where Euro-2012 football tournament matches will be played.

But the bomb blasts will unsettle Ukrainian authorities who have expressed confidence that they will be able to provide full security for the tens of thousands of European soccer fans expected to converge on the country in June and July.

Interior Minister Vitaly Zakharchenko immediately left for Dnipropetrovsk and ordered extra internal troops to the city to boost regular police. Parliament went into emergency session.

POLITICAL TENSION

The first blast occurred at a tram stop at 11:50 a.m. (0850 GMT), wounding 13 people and shattering the windows of a nearby tram and car.

The second explosion came 30 minutes later next to a cinema, injuring 11 people, nine of them children, the Emergencies Ministry said in a statement.

The third blast followed shortly afterwards next to a park, injuring 2 people, it said. The fourth explosion, also in the downtown area, caused no casualties, said the ministry whose estimate of injuries was lower than that of police.

Dnipropetrovsk is one of the former Soviet republic's biggest industrial hubs and was a key centre of the nuclear, arms and space industries in Soviet times.

It provided a springboard for former President Leonid Kuchma, who was in office from 1994-2005, to rise to power. It is also the birthplace of jailed opposition leader Yulia Tymoshenko.

Political tension is high in the country because of the detention of Tymoshenko who was jailed for seven years last October for alleged abuse-of-office which she denies.

Her imprisonment has prompted sharp criticism from Western governments which see her trial as political revenge by Yanukovich, who narrowly beat her for the presidency in February 2010.

Ukraine's parliament, where proceedings had been blocked for days by Tymoshenko's supporters, went into emergency session over the bombings.

Ukraine's neighbour, Russia, offered to help the authorities investigate the bombings. Poland, another neighbour and Ukraine's co-host of Euro-2012, said the bombings were an exceptional event.

"We have to treat the issue very seriously, not only because it's a tragedy, we've heard about casualties, many people wounded," Polish Prime Minister Donald Tusk told reporters.

"Any attack in our region is something rather exceptional, and I think we can talk of an attack at this point, while the context of the Euro 2012 makes us especially sensitive to such events."
