Union Home Minister P Chidambaram on Saturday sternly warned terror elements and said nobody will be allowed to play with India's unity "till the last drop of my blood".
"No terrorist or anti-national element will be allowed to play with India's unity and integrity till the last drop of my blood," Chidambaram told supporters in Sivaganga during election meetings.
"As the holder of India's home portfolio, I am warning all brands of terrorists that fatal hammer blows await them as the endeavour to safeguard ourselves," the home minister said.
He also recalled his performance as finance minister giving facts and figures as he addressed a series of meetings in his parliamentary constituency 350 km south of state capital Chennai.
Chidambaram has won six times from this constituency.
The warning against terrorists and anti-national element comes as over 30 people were arrested all over Tamil Nadu including Chennai, Thanjavur and the textile city of Erode earlier in the day for attempting to burn Indian flags to protest the centre's alleged aid to Sri Lankan military moves against the Tamil ethnic minority in the island.
