Now that over 48 hours have passed since two bomb explosions at Brussels' main airport and a downtown subway station killed at least 31 and injured hundreds more, there is enough information to piece together the complete chronology of these terrorist attacks.
Here, courtesy of the NYT, are the full details.
Two Belgian brothers, Ibrahim el-Bakraoui and Khalid el-Bakraoui, and an unidentified third man blew themselves up in the attacks. The blasts occurred four days after the capture of Salah Abdeslam, believed to be the sole surviving direct participant in the Paris attacks in November.

7:58 a.m.: Airport explosions
Two suicide bombers carrying large suitcases believed to contain explosives struck a departure hall at Brussels Airport. One of the bombers at the airport was Ibrahim el-Bakraoui, according to Frédéric Van Leeuw, the Belgian federal prosecutor. The two explosions were about nine seconds apart, the authorities said, and both hit check-in rows near the entrance, where video footage showed passengers were gathered.
The first bomb went off in check-in row 11, which has counters for Delta Airlines and Thomas Cook; the second exploded in check-in row 2, which has counters for Air Canada, Egyptair, GermanWings, Aer Lingus, Thai, TAP Portugal, Bulgaria Air and Lot Polish Airlines.
A third suspect, who has not been identified, was seen carrying a bag with another bomb more powerful than the first two, according to Mr. Leeuw. But the suspect fled and is now the subject of an intensive manhunt.
Below are photos of the departure hall as seen on Aug. 3, 2015, and after the explosions.

About 9:10 a.m.: Subway explosion
The second brother, Khalid el-Bakraoui, blew himself up in the second car of a train at the Maelbeek subway station in downtown Brussels during the height of the morning rush. The subway station is near many European Union buildings, including the European Parliament.

Many of the wounded were seen on Rue de la Loi, a normally busy street that runs through the heart of the so-called European quarter.

The Investigation After the Attacks
Officials believe the two men on the left in this airport surveillance photo were suicide bombers. Police asked for help identifying the man on the right.
Police officers conducted a series of house raids in Brussels. A taxi driver who said he took some of the suspects to the airport led the police to a house in the Schaerbeek neighborhood on Tuesday afternoon, where they uncovered explosives, detonators and a suitcase full of nails and screws, the Belgian prosecutor said.
Investigators also found a computer in a trash can on Rue Max Roos containing statements from Ibrahim el- Bakraoui.
