NUCLEAR war could break out "at any time" if India continues strikes, Pakistan's defence chief has warned as his country teeters on the brink of a conflict with India.
Defence Minister Khawaja Asif gave the stark warning in an interview with Pakistani TV channel Geo News as tensions between the two nuclear powers continue to reach boiling point.
The minister said: "If they [India] impose an all-out war on the region and if such dangers arise in which there is a standoff, then at any time a nuclear war can break out."
He added: "If they aggravate this then if a chance of war arises in which there is a sign of nuclear option being used on both sides, then the responsibility for that will be on India."
Pakistan's Prime Minister earlier blamed India for igniting an "inferno" in the region after bombing his country overnight and has now authorised his troops to fire missiles back.
Nuclear war in the region is feared to kill as many as 125million people - and the world has called on both sides to step back from the brink.

New Delhi, meanwhile, has said it is prepared to retaliate against Pakistan if it does return fire.
Speaking to Pakistan's parliament in Islamabad today, PM Shehbaz Sharif said: "the responsibility for ensuing consequences shall lie squarely with India."
He said: "The nation stands galvanized and resolute in the face of any further aggression."
Fears of all-out war are growing as Islamabad says India’s missile strikes deliberately targeted civilians – killing innocent men, women and children – in what it branded a “cowardly and unlawful act of war”.

India's Ministry of Defence said the strikes were in retaliation to a "barbaric" mass shooting in Kashmir last month, when 26 people were killed by gunmen.

Dramatic pictures from both sides of the border today show tanks on the move, soldiers on high alert and scenes of destruction as fears of full-scale war mount.

Following the strikes, Pakistan's Prime Minster, Shehbaz Sharif, said: “Pakistan has every right to respond forcefully to this act of war imposed by India, and a forceful response is being given."

Full statements from the two countries

“India has launched #OperationSindoor, a precise and restrained response to the barbaric #PahalgamTerrorAttack that claimed 26 lives, including one Nepali citizen.
“Focused strikes were carried out on nine #terrorist infrastructure sites in Pakistan and Pakistan-occupied Jammu and Kashmir, targeting the roots of cross-border terror planning.

“This operation underscores India’s resolve to hold perpetrators accountable while avoiding unnecessary provocation. A detailed briefing on the operation will follow later today.”

“Pakistan has every right to respond forcefully to this act of war imposed by India, and a forceful response is being given.
“The entire nation stands with the Pakistani armed forces, and the morale and spirit of the entire Pakistani nation are high.
"The Pakistani nation and the Pakistani armed forces know how to deal with the enemy.
“We will never allow the enemy to succeed in their nefarious goals.”
Tensions between the two nuclear-armed rivals hit boiling point after 26 tourists were shot dead when gunmen opened fire at a beauty spot.
Pakistan's defence minister previously warned that a row over the mass shooting in Kashmir could lead to an "all-out war" with India.
Khawaja Asif said his country would "respond in kind" to any attack by New Delhi and said the world should be "worried" about the prospect of a full-scale conflict.
He told : "We will measure our response to whatever is initiated by India. It would be a measured response".
"If there is an all-out attack or something like that, then obviously there will be an all-out war."
Asked whether the international community should be concerned, he replied: "Yes, I think so. The clash between two nuclear powers is always worrisome...
"If things get wrong, there could be a tragic outcome of this confrontation."
But he also added: "I hope there is some reconciliation and some negotiation... some efforts to resolve this issue peacefully."

Why are India and Pakistan enemies?
Disputes between India and Pakistan over the region of Kashmir date back decades.
The Muslim-majority territory was fought over in the aftermath of both countries' independence following the partition of India in 1947.
War between India and Pakistan would break out again in 1965 - which ended in a ceasefire.
Kashmir's control remains divided to this day, and tensions frequently flare up over the region.
India also fought Pakistan wars in 1971 and 1999 - with the conflict in the 70s resulting the independence of Bangladesh from Pakistan.
Both nations are nuclear armed powers.
