"I salute the martyrs of the armed and police forces and convey my deepest condolences to the families of the civilians killed in the deplorable and deliberate terror attacks in Jammu and Kashmir," the Congress Vice President said in a statement.
He further said that these destabilising attempts, being escalated from across the border in Pakistan, need to be crushed with resolve.
"And the Congress Party stands firm with the people of the state and government agencies in their efforts to counter terror and terrorists," Gandhi said.
The attacks and gun battles with security forces which in all left 21 people dead also included a top commander of Pakistan-based terror outfit LeT and seven militants. Srinagar and Shopian were the other two places where the militants struck.
They came just three days after a 72 per cent voter turnout was registered in the second phase of incident-free Assembly elections in Jammu and Kashmir on Tuesday in a rerun of record polling in the first phase.
