A homemade nail bomb has been detonated in busy central Budapest, seriously injuring two police officers.
Hungarian police are still unclear if the explosion was a terrorist attack, and are looking into any connections with terrorism.
The bomb exploded at around 10:30 pm local time, just days before an important vote on the country’s migration rules is set to take place.
The two officers, who were on patrol at the time of the explosion, were seriously injured, and taken to hospital.
Chairman of National Security Committee, Zsolt Molnar, said: “We haven’t yet received any confirmation that it was a jihadist attack, but we are still investigating every potential theory.
“It is clear that the purpose of the attack was to murder two of our officers,” The Express reported.
A manhunt is currently underway for a man believed to be between the ages of 20 to 25. It is thought he was wearing a white fishing hat at the time of the explosion.
Investigating officers have said that it is unclear as to whether the suspected attacker is still in Hungary, or if he has left the country.
Boarders have been tightened, and security has been upped, as a result of the incident, which made glass windows shatter.
A reward of £28,000 has been put forward by authorities, for anyone who can point them in the right direction to finding the suspect.
Witnesses at the scene of the explosion first thought it had occurred due to a gas leak.
