Mounting pressure on its ally over the border row issue, the Shiv Sena on Saturday warned BJP that it would snap ties with it if its government in Karnataka continued to 'torture' Marathi-speaking people.

"BJP government in Karnataka used force against Marathi people protesting the Assembly session at Belgaum, a border district, and arrested senior leaders like ND Patil," Leader of Opposition in Maharashtra Assembly Ramdas Kadam said from Belgaum.
