A suicide attack on Moscow’s Domodedovo airport claimed the lives of over 30 people and injured many more on Monday, officials said.

Eyewitnesses said two terrorists blew themselves up as people emerged from the international arrivals zone at 16:40.

The death toll from the deadly blast which occurred on Monday in Moscow's Domodedovo International Airport has risen to 35, the airport's press secretary, Yelena Galanova, said.

According to the Russian Health Ministry, 130 people were injured in the blast.

Airport employees broke down the wall between the main airport and the arrivals zone to allow passengers to escape the scene of destruction.

Prime Minister Vladimir Putin has been informed about the blast. President Dmitry Medvedev pledged assistance to the families of the dead and those injured in the attack.

Russian transport watchdog Rostransnadzor said on Monday it had instructed all airports in the country to impose enhanced security measures, including passenger screening at entrances.

The instructions followed Monday's suicide bombing at Domodedovo Airport near Moscow that killed over 30 and left at least 130 injured.

"Urgent measures to prevent terrorist attacks on transport facilities must be taken," the watchdog said.

Security has been tightened at other airports in the capital and the city’s metro system, which was hit by twin suicide bombings in March 2010. Chechen militant leader Doku Umarov claimed responsibility for those attacks, which killed 39 people, and warned that “war” was coming to Russia’s streets.

A law enforcement source told RIA Novosti that the security services were aware that terrorists were planning an attack on a Moscow airport, but were unable to locate and detain the three suspects they had been searching for.

Comments by Russian bloggers suggested that there was free access, without security checks, to the arrivals gates.
