As EU interior and justice ministers prepare for Thursday's talks in Brussels to discuss how to deal with jihadist attacks in Europe, the BBC's Katya Adler in the Belgian capital predicts that the meeting will not be an easy one.
Taking into account a forthcoming referendum in Britain on EU membership and recent strident nationalistic statements by some EU members, our correspondent says the idea of a more unified European response to the jihadist threat is "not going to be very digestible" for some European governments.
'This is political violence, not a war' - former IS hostage Nicolas Henin
Nicolas Henin, the French journalist who was for months held hostage by the so-called Islamic State in Syria, writes in the Guardian newspaper that while the Brussels attacks had a lower death toll than those in Paris last November, they have a different significance.
Quote Message: The Brussels attack marks the migration of terror from one country to the next. Suddenly everyone is saying: who is the terrorist, and where will they strike next – the UK? Germany? The Netherlands?

But while Khalid and Brahim el-Bakraoui and, reports say, Najim Laachraoui performed their duty to die as "cannon fodder" for IS, Mr Henin says that the unwillingness to kill himself of another militant - Salah Abdeslam, who has been arrested - represents an opportunity.
Quote Message: First in Paris and now in Brussels, he has twice refused to meet his death. Perhaps there are signs of hope in this, for it shows that if there is a weakness in Isis, it is that there are humans in its ranks

Mr Henin says how Europe reacts now will be crucial - but, he says, the omens are not good. Already French President Francois Hollande has, he says, "fallen into the trap" of referring to this challenge as a war.
Quote Message: We have seen large-scale political violence before in our history. If we adopt a militaristic, warlike vocabulary, there will be no way back from that. We will only strengthen our enemies

Limited metro service in Brussels on Thursday

The 'explosive of choice' used by terrorists in Brussels, Paris and London
When Belgian police raided an apartment in the Schaerbeek area of Brussels, linked to the attackers, they found bomb-making materials, including 15kg (33lb) of TATP.
This powerful DIY explosive was also used by terrorists in Paris and in the 2007 London bombings.
Details are continuing to emerge about what happened yesterday, including the identities of the suicide bombers. A manhunt is still underway for a third airport attacker, so far unnamed, whose device failed to detonate.
Response to IS in Iraq and Syria 'more promising than efforts in Europe'
Daniel Byman, an extremism expert at Georgetown University and the Brookings Institution, writes in the New York Times that while the group Islamic State (IS) may be on the defensive in Iraq and Syria, it is lashing out abroad and Europe is emerging as a "key battleground".
Mr Byman says that returnees from Syria and Iraq are linking up with locals, creating a "self-sustaining cycle of violence".
Quote Message: The first volunteers were motivated primarily by adventure or out of a sense of defending their community, but now friends are recruiting friends, promising glory and God

Quote Message: Across the Continent, Muslims often feel alienated from the broader population. In the US, many plots are disrupted because the American Muslim community reports them to the police and the FBI; such trust is lacking in Europe

Quote Message: The rise of far-right, xenophobic political forces, like the National Front in France or Alternative for Germany, will do little to improve relations between European Muslims and their governments

'We must find the former Belgium again - a country where we smiled at each other'
BBC Monitoring
In its special live coverage of the aftermath of the Brussels attacks, Belgian public service broadcaster RTBF continues to alternate between news updates, studio discussions with security experts and footage showing the crowds gathered in the Place de la Bourse in Brussels to pay tribute to the victims of the attacks.
Many people lit candles as darkness fell, and Moroccan, Tunisian, Turkish and other flags from all over the world were shown displayed alongside the Belgian flag.
One woman told the RTBF interviewer that she had come with her family in order to express her solidarity and "to find again the former Belgium". Asked what this Belgium meant to her, she said it was a country "in which people used to smile at each other and talk to each other".
