Police said they were investigating the explosion, which came at a time of high tension in Sri Lanka following the Easter Sunday suicide bomber attacks on the island state that killed 359 people and wounded about 500.
Local media also reported that the road opposite Bandaranaike International Airport was reopened after being temporarily closed due to a suspicious vehicle. Operations at the airport, which were suspended, also returned to normal. The Kurunegala bus stand was also evacuated and special search operation is underway.
Outrage over the terror attack rose after the Sri Lankan government admitted that "major" intelligence lapses led to the horrific blasts and asked two top security officials to resign. The Islamic State has claimed responsibility for the attacks and identified the seven suicide bombers who carried out the devastating blasts.
