A Pakistan government minister has accused India of plotting a fresh military attack.
Foreign minister Shah Mehmood Qureshi said the country has "reliable intelligence" that an attack is imminent in mid-April.
India has dismissed the claims as “war hysteria”.
Diplomatic tensions between the neighbouring countries have been heightened since Pakistan-based militants killed dozens of Indian troops in the disoputed region of Kashmir in February.
India responded with air strikes on what it said was a militant training camp in Pakistani territory.
Soon afterwards, Pakistan shot down an Indian jet and captured its pilot. He was handed back to India days later.
