In her tweets, BJP leader Sushma Swaraj also said that the party will "support" the Congress-led United Progressive Alliance (UPA) government if it takes "tough" decisions against Pakistan.
"I spoke to National Security Adviser S.S. Menon yesterday. I told him to convey to the Prime Minister that what has happened on the LOC is unacceptable," Sushma Swaraj tweeted.
"However, there is no response from the government so far. The government must go in for tough measures and we will support the government in such decisions," she added.
"Unfortunately, we have a very weak government in the country. And weak governments are incapable of taking tough decisions," the BJP leader said.
"It is matter of honour for the country. It is question of the morale of our armed forces. The government has to act. And the government has to act tough," she further said.
In a brazen violation of the 2003 ceasefire, Pakistani troops shot dead and beheaded two Indian soldiers along the LoC in Jammu and Kashmir Jan 8, sparking a diplomatic row between the two nations.
