Talking tough, India today blamed Pakistan Army for the increasing infiltration attempts accompanied by "unusual" border ceasefire violations and questioned Pakistan's sincerity to improve ties between the two countries.
Defence Minister A K Antony said the security forces have observed that the terrorists trying to infiltrate were well equipped and prepared to sustain for a longer period while carrying out their activities.
"In spite of preventing the infiltrators or minimise infiltration attempts, still these attempts are going on increasing. This means this is going on with the support of elements across the border. I am sure that nothing can happen there without the knowledge and tacit or sometimes open support of Pakistan," he told reporters here.
"On Pakistan side, border is completely guarded by Pakistan Army. How can terrorists try to infiltrate into India without the knowledge and support of Pakistan? How can the terrorists embolden to increase the attempt to infiltrate without the tacit or sometimes open support of their armed forces? That is a question worrying us," he said.
Antony said there have been "unusual developments" of ceasefire violations on the International Border also this year.
"Ceasefire violation is still continuing. But this year, unusual developments are taking place. So far, ceasefire violations were taking place only on LoC. Suddenly, there is a series of ceasefire violations on the international border. That is more a matter of serious concern," he said.
