As Belgian authorities continue to hunt Wednesday for one of three suspects in the deadly attacks in Brussels, a connection is emerging between the men who carried out the airport and metro bombings and the terror cell behind the Paris attacks.
Belgian officials say two brothers – Ibrahim el-Bakraoui, 29, and Khalid el-Bakraoui, 27– were identified as two of the suicide attackers who targeted the airport and subway station in Brussels. Police are still looking for a third, unidentified attacker.

Several Belgian news outlets reported the Bakraoui brothers were wanted in connection with an anti-terror raid at an apartment in the Forest neighbourhood of Brussels on March 15. During the raid police found fingerprints belonging to Salah Abdeslam, who was captured March 18 and is suspected of having participated in the Paris attacks.
The so-called Islamic State claimed responsibility for both attacks.
Here is a look at events leading from the November attacks in Paris to the bombings in Brussels.
Nov. 13, 2015: A series of co-ordinated attacks rock Paris in one of the worst attacks on French soil since the Second World War.
Gunmen and suicide bombers target a number of restaurants, the Bataclan concert hall and the Stade de France, killing 130 people and injuring hundreds more.
“This is a terrible ordeal which once again assails us. We know where it comes from, who these criminals are, who these terrorists are,” said French President Francois Hollande following the attacks.
“In these difficult moments, we must — and I’m thinking of the many victims, their families and the injured — show compassion and solidarity. But we must also show unity and calm.”
Nov. 18, 2015: The suspected mastermind of the deadly Paris attacks, Belgian Abdelhamid Abaaoud, 27, is killed along with his female cousin during a police raid in the Paris suburb of Saint-Denis, according to Paris prosecutor Francois Molins.
Nov. 21, 2015: Brussels is placed in lockdown with soldiers flooding the streets in response to a what officials said was a threat of a series of co-ordinated attacks at different locations throughout the capital.
Nov. 22, 2015: Police raids are carried out in Molenbeek, a district of Brussels home to many of the Paris attackers and previously linked to other European terror attacks. A total of 16 people are arrested.
Molenbeek, a traditionally working-class neighbourhood, has become home to an increasing number of radicalized Muslims. Disenfranchisement, unemployment, and a complex system of regional governments have led to growing terrorism concerns, say experts.
Nov. 24, 2015: Belgian authorities charge a fifth suspect in the Paris attacks as Brussels remains under lockdown. An explosive vest containing bolts and the same type of explosive used in the Paris attacks is found in Chatillon-Montrouge, south of Paris a day earlier.
Nov. 25, 2015: The French parliament votes to continue air strikes against the Islamic State group in Syria.
Dec. 10, 2015: Belgian prosecutors say they found a fingerprint belonging to suspect Salah Abdeslam during a search of an apartment in Schaerbeek in Brussels. They believe the apartment served as a bomb factory for the Paris attacks.
Three handmade belts which could have been intended to transport explosives, as well as bomb-making equipment and traces of explosive residue were also found in the apartment.
The international manhunt for Abdeslam continues almost four weeks after the Paris attacks. Ten suspects have been arrested.
Jan. 18, 2016: Police in Morocco arrest a Belgian man of Moroccan descent, claiming he is linked to the Islamic State group and had a “direct relationship” to the attackers who killed 130 people in Paris in November, according to the country’s interior ministry.
March 18, 2016: After four months on the run from authorities, Abdeslam is captured by Belgian police in a raid in the Molenbeek district of Brussels. Abdeslam is shot in the leg during the arrest and two other men are also detained.
March 22, 2016: Four days after Abdeslam is captured, Brussels is hit by attacks on the Zaventem airport and the city’s metro system, near the European Union buildings.
“What we feared has happened, we were hit by blind attacks,” Prime Minister Charles Michel told reporters during a news conference.
Authorities say at least 30 people were killed and more than 250 were injured.
