( CNN ) -- Two bombs went off at separate locations in the Northern Ireland city of Londonderry , police said Thursday . The Police Service of Northern Ireland said people had been moved from both areas after telephone warnings and there were no reports of injuries . One of the blasts was on Strand Road , near government offices and police headquarters . The other was near a tourist office at Foyle Street . The police commander for the city , Chief Superintendent Stephen Martin , branded the attacks `` reckless . '' He praised his officers for quickly evacuating businesses and homes , including many elderly residents . `` Thankfully we are not dealing with mass casualties or worse this evening , '' said Martin . `` The people of Derry do not want this - it is cowardly and callous . '' Londonderry , Northern Ireland 's second largest city , has a Catholic majority and is known as Derry by many residents . Local politicians are blaming Irish Republican Army splinter groups for planting the bombs . There have been several attacks by so-called `` dissident republicans '' in the city during recent years since the mainstream IRA declared a cease-fire . The IRA for decades fought against British authorities in Northern Ireland , but has since renounced violence . The former Social Democratic and Labour Party mayor of the city , Irish nationalist Colum Eastwood , condemned Thursday 's attacks . `` This was an attack on the people of Derry by the enemies of Ireland . Those behind this are engaged in a futile and morally bankrupt campaign . '' Leader of the pro-British Ulster Unionist Party , Tom Elliott , said , `` I have no doubt the bombs are the work of so-called `` dissident '' republican terrorists . `` We have seen this type of attack before during the troubles when the IRA blitzed Londonderry on a regular basis , '' Elliott said . `` Those attacks failed to break the will of the unionist people and these attacks will fail , too . These attacks further no cause . '' Elliott called for a security crackdown by British authorities and urged anyone with information on the bombers to give it to police . `` This type of fascism was part of our past . It has no place in our future , '' he added .
