Angry MPs of the MDMK and PMK created uproar in the Lok Sabha on Wednesday in support of Sri Lankan Tamils, forcing Speaker Somnath Chatterjee to adjourn the house for 25 minutes.
The MPs, wearing black shirts, shouted slogans and walked up to the well of the house expressing their protest against External Affairs Minister Pranab Mukherjee's suo motu statement in the house over the Sri Lankan situation.
"Stop the war in Sri Lanka" and "we are not satisfied with the statement" (of the minister) were among the slogans.
Tamil members of some other parties also backed the two parties' MPs.
The members also shouted that the Indian government should interfere for a "permanent ceasefire" to save Tamil civilians.
Mukherjee had said the Liberation Tigers of Tamil Eelam (LTTE) would "best serve the interest of the Tamils by immediately releasing all civilians (under its control) and laying down arms".
Pointing out that the LTTE was an outlawed group in India, the minister added that it "has done much damage to the Tamil community".
The Indian government, he added, "is ready to facilitate the evacuation of civilians trapped in the area of conflict, working with the government of Sri Lanka and the ICRC (International Committee of the Red Cross)".
