MOSCOW/BRUSSELS - Russian Foreign Minister Sergei Lavrov on Wednesday called for Europe to drop its "geopolitical games" and unite behind efforts to fight terrorism, a day after bomb attacks in Brussels killed around 30 people.

"I really hope that Europeans, in the face of the terrible threat of terrorism that occurred yesterday in Brussels, will put aside their geopolitical games and unite to prevent terrorists from acting on our continent," Lavrov was quoted by Russian agencies as telling visiting German counterpart Frank-Walter Steinmeier.

Meanwhile, Turkish President Tayyip Erdogan said on Wednesday that one of the attackers in the Brussels suicide bombings was deported last year from Turkey, and Belgium subsequently ignored a warning that the man was a militant,. Erdogan's office identified the man as Ibrahim El Bakraoui, one of the two brothers named by Belgium as responsible for the attacks that killed at least 31 people in Brussels on Tuesday and were claimed by the Islamic State group. Belgian officials did not respond to requests for comment.

Europe is facing a security crisis after Tuesday's triple bombing in Brussels, which came on the heels of the November bomb and gun assaults in Paris that killed 130 people.

Russia's call to unite against terrorism comes amid a diplomatic push over the five-year conflict in Syria.

Steinmeier was in Moscow for meetings with Lavrov and President Vladimir Putin Wednesday, while US Secretary of State John Kerry touched down in the Russian capital ahead of talks with the duo Thursday.

The West is looking to size up the Kremlin's game plan after Putin's surprise announcement on March 14 that Moscow was withdrawing the bulk of its forces conducting air strikes in support of President Bashar al-Assad in Syria. Moscow launched a bombing campaign in September saying they were striking the Islamic State group and other "terrorists" before they hit Russia, but the West said they mainly targeted Assad's more moderate opponents.

Steinmeier said last week that Russia's drawdown in Syria could increase pressure on Assad to "negotiate in a serious way", but peace talks with the opposition in Geneva have failed to make much headway.

"I personally cannot imagine that in light of 250,000 people killed and 12 million refugees, Assad can become a leader acceptable to all segments of the population," Steinmeier told Russia's Interfax news agency Wednesday.

An unprecedented ceasefire negotiated by Russia and the United States has largely held in Syria since February 27, but it does not apply to militants.

Many Russian officials, including Putin, have echoed Lavrov's call for unity in the fight against terrorism.

"The fight against this evil calls for the most active international cooperation," the Kremlin said Tuesday.

A Russian jet on its way from Egypt's Sharm el-Sheikh resort to Saint Petersburg was brought down in October by a bomb, killing all 224 people on board in an attack claimed by the Egyptian-branch of IS.

Ties between Moscow and the West have plunged to their lowest point since the Cold War over Russia's intervention in war-torn Ukraine but the Kremlin's Syria gambit thrust Putin back into the centre of international diplomacy.

Other Russian officials and politicians have used the Brussels attacks to rebuke the West.

The outspoken head of parliament's foreign affairs committee, Alexei Pushkov, tweeted Tuesday that while NATO chief Jens Stoltenberg was "battling an 'imaginary Russian' threat and stationing troops in Latvia, people are being blown up under his nose in Brussels".

Foreign ministry spokeswoman Maria Zakharova said she deplored "double standards" in the fight against terrorism.

In Brussels, they came from Peru or Morocco, from North America or Europe, and their lives - as parent, eurocrat, sportsman or missionary - were just as diverse.

That is the emerging picture of the hundreds of people fated to be killed or wounded in the triple bomb attack in Brussels on Tuesday.

Belgian Foreign Minister Didier Reynders told Belgian television RTBF that there were around 40 nationalities were among the dead and wounded.

They included citizens of Britain, Colombia, Ecuador, France, Portugal and the United States, as well as three to four staff from the EU's executive arm, the European Commission.

The broad range of nationalities reflects the cosmopolitan nature of Brussels - home to many migrants to Belgium as well as the institutional capital of the 28-nation European Union.

Among the first fatalities to be named was a Peruvian woman, Adelma Marina Tapia Ruiz, who had been living in Belgium for six years and was travelling with her journalist husband and young twin daughters.

One of their daughters was wounded by flying debris in one of two blasts at Brussels' Zaventem airport.

"They took away everything she wanted to do with her life," her brother Fernando Tapia told Peruvian media, after she was identified by the foreign ministry in Lima.

A Moroccan woman was also killed in a third blast at a metro train at a station close to the European Union's institutional hub, according to the Moroccan news agency MAP.

According to an ongoing toll provided by the Belgian health ministry, 31 people were killed and 270 were injured.

It was the bloodest terror assault in Belgium's history.

French Prime Minister Manuel Valls on Wednesday said 10 French nationals had been injured, four of them seriously.

In London, Downing Street said one British national was missing and four were injured, three of whom were being treated in hospital.

Officers from the Belgian federal police's disaster victim identification team were working at the sites of both attacks, poring over the remains in a grisly process to identify the casualties.

Mason Wells, 19, was one of three US missionaries from Utah who were seriously wounded in the blasts at the airport, the Church of Jesus Christ of Latter-day Saints said in a statement.

US media reports said that in a dark twist of fate, Wells had a similarly close call three years ago while in Boston accompanying his mother who was running the marathon.

The event was the target of a terror attack that killed three and wounded scores more.

NBC News, quoting Wells' family, said he was also in Paris in November when the French capital was rocked by a series of attacks.

Wells "has burns to his hands and legs and some to his face," a family friend, Lloyd Coleman, told Utah's Deseret News daily.

The US Air Force also said one of its service members and several of his relatives were also injured.

Basketball player Sebastien Bellin, who was pictured lying on the airport floor covered in blood, has had surgery, his father, Jean Bellin, told CNN.

"He is obviously stunned. The first words out of his mouth were 'You wouldn't believe the carnage I saw around'," the father said.
