At least 22 people were injured Friday morning after a “terrorist incident” in a London subway station during rush hour.
A homemade bomb exploded on the crowded subway in what police said was a terrorist attack – Britain’s fifth this year. Most of the people injured had “flash burns,” police said.
No deaths have been reported.
Friday’s attack isn’t the first this year that occurred on a train. Read on for a look at other train attacks.
St. Petersburg, Russia – April 2017
A bomb was detonated between Sennaya Square and Technology Institute, two busy stations in the center of the Russian city, killing 14 people -- including the suicide bomber -- and injuring dozens of others, according to Sky News.
Police said Akbardzhon Dzhalilov, 22, walked into the subway with a backpack that held the bomb on April 3. Dzhalilov was linked to radical Islamic terror groups by investigators.
A second device was found at another station nearby and deactivated, Sky News reported.
Several people were arrested for connection to terrorism following the attack.

Brussels, Belgium – March 2016
ISIS claimed credit for a series of bombs in Brussels that killed 32 people and injured more than 100. The bombs went off in the crowded airport and subway during rush hour in the Belgian capital on March 22.

A bomb exploded April 11 in a packed metro station in Minsk during rush hour, killing 15 people.

The station is near many government buildings.
Two young men were put to death in 2012 after being convicted of carrying out the attack. The European Union and human rights groups opposed the execution as they said the trial was flawed and the men were framed, according to The Guardian.
Moscow, Russia – March 2010
Female suicide bombers killed 38 people when they detonated explosives in two of Moscow’s busiest subway stations on March 29. The attack came during morning rush hour.

A Russian court jailed 10 people – four for life – in May 2012 for their involvement in the blast, according to the BBC.
London, England – July 2005
Four suicide bombers killed 52 people and injured hundreds more on July 7 when they detonated explosives in four different transportation locations. Three were detonated in underground train stations and one on a double decker bus.

The bomb detonated near the front of the train at Edgware Road killed six people; the bomb detonated near the front of the train near Aldgate killed seven people; the bomb detonated in the first car of the train at Russell Square killed 26 people.

The explosions happened just three days before Spain’s general election.
