There's no doubt the Brussels terrorist attacks are the most violent to hit Europe since the November attacks in Paris that killed 130 people.
But this is not the first, or even the second, terrorist attack in that time — though certainly this will be the first- or second-most covered by Western media. Since the Paris terrorist attacks on November 13, there have been literally hundreds of terrorist attacks around the world. Factor out the ongoing conflicts in Afghanistan, Iraq, Libya and Syria and you still have dozens of attacks over the past five months.
Some like the attack in San Bernardino, California, were certainly well-reported. The attack in Ivory Coast earlier this month also was widely covered. This weekend alone, ISIS claimed responsibility for a suicide bombing that killed 25 Iraqis at a soccer stadium, and more than 65 people were killed in an attack that targeted Christians in Lahore, Pakistan.
But other attacks have flown under the radar. Here are some of the most significant terrorist attacks in the past four months.
Bamako hotel attack: November 20, 2015
A group of al-Qaeda-linked militants took 170 people hostage, ultimately killing 20, during a mass shooting at a Radisson Blu hotel in Bamako, the capital of Mali in West Africa.
Malian commadoes ultimately raided the hotel and freed the hostages, killing the two assailants. Another seven people were wounded.
Tunis bus attack: November 24, 2015
A bus loaded with Tunisian presidential guards was struck by a suicide bomber linked to the so-called Islamic State.
The lone bomber killed 13 people in what was the third significant attack attributed to ISIS in Tunisia in 2015.
San Bernardino attack: December 2, 2015
In the attack, 14 people were killed and another 22 were seriously injured.
A manhunt ensued and the two perpetrators, Syed Rizwan Farook and Tashfeen Malik were killed in a shootout with police. The FBI said the two shooters were "inspired" by ISIS, but conducted the attacks on their own.
Istanbul bombing: January 12, 2016
A suicide bombing in a popular central square in Istanbul, Turkey's largest city, left 13 people dead and 14 people injured. All of the dead were foreigners.
The perpetrator was identified as Nabil Fadli, an ISIS follower from Syria.
Jakarta attacks: January 14, 2016
A series of suicide bombings and shootings in Indonesia's capital left eight people dead, including four assailants. Another 24 people were wounded.
ISIS claimed responsibility for the attack, which was conducted by an unknown number of assailants. Though four assailants were killed, as many as 10 others may have been involved.

Ankara bombing: February 17, 2016
Kurdish freedom fighters attacked a convoy of buses killing military personnel and civilians during evening rush hour. At least 29 people were killed and another 60 people were injured.
The attack, which was carried out by a car bomb, was targeted at military forces, the Kurdistan Freedom Falcons said. One perpetrator died in the attacks.
Mogadishu hotel attack: February 26, 2016
A group of militants linked to al-Shabbab killed at least 15 people and left others wounded after a suicide bomber detonated a bomb at the gate of the SYL hotel in Mogadishu.
Four gunmen forced their way past the first security barrier before being killed in a shootout with guards manning the hotel's last security line. More than a dozen people were wounded.
Grand-Bassam resort shootings: March 13, 2016
The hotel is popular with ex-pats in Ivory Coast. At least three assailants involved in the attack were killed and another as many as three escaped.
Ankara bombing: March 13, 2016
A second attack in Ankara this year saw the deaths of 37 people and another 127 people injured. As with the first attack, the Kurdistan Freedom Falcons claimed responsibility for the assault.
The perpetrator was killed in the attack, which targeted a transportation hub. The Kurdish group said civilians weren't its main target, but more civilian casualties were inevitable.
Istanbul bombing: March 19, 2016
At least four people were killed by a suicide bomber that has rocked the residents of Istanbul to their core. Another 36 people were wounded by the attack on Istanbul's main shopping street.
About one-third of the injured were foreign tourists. Thus far, no one has claimed responsibility.
