Moscow, Jan 25 (Agencies): Russian President Dmitry Medvedev, on Tuesday, said that Monday’s bomb blast at Moscow’s Domodedovo International Airport, that killed 25 and injured up to 180, was a ‘well planned terrorist act’.

According to preliminary reports, a suicide bomber blew himself up on Monday afternoon in the airport's crowded international arrivals hall on, killing at least 35 people and injuring up to 180.

'This is a terrorist act, this is grief, this is a tragedy,' Medvedev said. 'I hope law enforcement bodies are able to quickly determine the main explanation [for the terrorist act] and conduct an investigation,' the President added. 

Pledging assistance to the families of the dead and the injured people in the attack, President Medvedev announced that he would postpone his visit to the Davos Economic Forum in Switzerland where he was scheduled to make an opening address. 

'Taking into consideration the location and other indirect indications, this was a well-planned terrorist act aimed at killing as many people as possible,' Medvedev told journalists, adding: 'Medical personnel are trying to help those in need, there is a large number of injured.' 

A spokesman for Russia's national anti-terrorism committee (NAC) said on Tuesday that insufficient security measures in Moscow's Domodedovo Airport were to blame for Monday's deadly blast. 

The international community condemned the blast, with NATO Secretary-General Anders Fogh Rasmussen saying he was 'deeply disturbed' by the attacks. 

'I strongly condemn this outrageous act of terrorism against the Russian people,' US President Barrack Obama said in a statement. 

British Prime Minister David Cameroon offered the Russian authorities 'complete support' and 'made clear that the people of Britain stood with the people of Russia in the face of these events,' a Downing Street spokesperson said.
