Spokesperson of the Sri Lanka Monitoring Mission (SLMM) Vilja Kutvonen told BBC Sandeshaya that Jaffna Central College principal, K. Rajadurai succumbed to injuries after been shot near the Jaffna library on Wednesday.

On Tuesday, Kopay Christian College principal Nadarajah Sivakadacham was killed by gunmen in front of his home in Kopay North.

Students protest

Kopay Christian College students in their hundreds mounted a protest in Jaffna on Wednesday blocking the Kopay junction.

Reports from Jaffna say that students from other schools also joined the protest that stopped the traffic for nearly four hours.

Protesting students called for an impartial inquiry to bring the responsible for the killing to justice.

Sri Lanka Army (SLA) said that the police "diverted traffic and minimised inconvenience to the public".

N Sivakadadcham was the Kopay division organiser of the Pongu Tamil movement.

The Pongu Tamil movement is known to have close links with Tamil Tigers.

Responsibility

LTTE Jaffna political wing leader C Ilamparithi told the BBC that both the killings are the work of the state military intelligence with the help of Eelam Peoples Democratic Party (EPDP).

Leader of the EPDP, Jaffna Development Minister Douglas Devananda denied the allegation saying that the Central College principal was a "close friend".

He added that the Kopay Christian College principal was a LTTE sympathiser until recently.

The SLA as well as the EPDP leader blamed the killing on the Tamil Tigers.

A correspondent from the North said that killing of scholars has sent a shockwave through Jaffna.
