Chennai (PTI): MDMK leader Vaiko and scores of his supporters were taken into custody here on Friday when they tried to take out a rally on the Sri Lankan Tamils issue, defying prohibitory orders,police said.

Vaiko and his supporters raised pro-LTTE slogans and condemned the Sri Lankan government for its alleged killing of the Tamils in the ongoing ethnic strife in the island nation.

Vaiko also charged the Indian government with supplying arms and ammunition to Sri Lanka.

Later, Vaiko told reporters his party would boycott the October 14 all party meeting,convened by the Chief Minister M Karunanidhi on the Sri Lankan Tamils issue, as it was just "eye-wash".

He said the Chief Minister was convening the meeting at a time when he could not "pressure" the Centre to raise the 'killing' of Tamils with the Sri Lankan government as well as unable to ensure supply of relief material to the "suffering Tamils" in the island nation.

AIADMK leader Jayalalithaa had on Thursday demanded that the Centre supply humanitarian aid to the Tamils in Sri Lanka.
