A law drafted by the European Parliament and endorsed by other political groups would restrict access to chemicals and ingredients used to make homemade explosives.
European Union residents will now have to obtain a license to obtain products that can potentially be used to make bombs.
The Parliament cited confessed Norwegian mass murderer Anders Behring Breivik’s bombing in Oslo last summer, which used a homemade explosive device.
The draft law recommends would affect bomb-making ingredients including swimming pool tablets and fertilizers—hydrogen peroxide, nitric acid and nitromethane.
“This is a huge step forward in the fight against terrorism and organized crime,” rapporteur Jan Mulder said in a statement.
Presently, EU member states have different laws regulating the purchase of homemade bomb ingredients.
“Due to differing national rules, they may be restricted or controlled in one country, yet freely available in another,” a statement from the Parliament reads.
