In December, a student killed 14 people and wounded 25 before shooting himself dead at Prague's Charles University in the capital's historic centre.

The bill was submitted by the government last June, months before the shooting, and it orders gun sellers to report suspicious purchases.

The measures, which have yet to be passed by the senate and signed into law by the president, will still allow Czechs to buy, own and carry guns.

It also enables the police to seize weapons because of security risks and introduces stricter medical checks for gun owners.

Czech media said the university gunman, who also shot three other people including his father and a two-month-old baby in a pram before the university killings, owned eight weapons.

The 24-year-old student had taken a loan to buy his arsenal including a semi-automatic rifle, ammunition and silencers, they reported.

The interior ministry is now planning an amendment that will further tighten the rules for gun ownership, due to be submitted to parliament this year.
