Thiruvananthapuram: Unidentified miscreants on Tuesday vandalised and later set ablaze offices of BJP and RSS in the Kannur district of Kerala.

One RSS worker was also hacked by the miscreants.

The incident happened at Payyanur area of Kannur early today after an unruly crowd of people unleashed an attack against Mararji Bhavan functioning as the BJP office.

No one was inside it at the time of the incident, police said.

BJP workers alleged that the CPI-M was behind the attack. The party called for a strike in Payyanur tomorrow.

Only a forensic examination will reveal if the office was set on fire or a petrol bomb was hurled. It has suffered some damage, they said.

The police have started an investigation into the incident.

According to PTI, BJP workers have accused CPI-M of being behind the attack. The party has called for a strike against the incident in the Payyanur on Wednesday.

However, CPI-M workers alleged that BJP activists hurled three country bombs at a motorcycle rally taken out by them at Payannur in the evening on the first death anniversary of CPI-M worker Dhanraj who was killed allegedly by RSS activists on July 11 last year.

Police said a few houses of workers belonging to both parties were attacked.

Some persons have been taken into custody in connection with the incidents. The situation is under control, they said.

On the other hand, at least nine CPI(M) workers were left injured in a bomb attack in Kakkampara area of Kannur earlier today.

Further details awaited.
