Ammon News - A blast was heard in Pakistan's Lahore city on Thursday, broadcaster Geo TV and a Reuters witness said, a day after Indian strikes on multiple targets in the country and fears of a larger military conflict between the nuclear-armed neighbours.

There was no immediate word on the reason for the blast.

India hit infrastructure in Pakistan in the early hours of Wednesday, two weeks after it accused the Islamic nation of involvement in an attack in Indian Kashmir in which 26 people - mostly Hindu tourists - were killed.

Islamabad had denied the accusation and vowed to retaliate to the missile strikes, also saying it shot down five Indian aircraft. The Indian embassy in Beijing termed reports of fighter jets being shot down as "misinformation".

Pakistan says at least 31 of its civilians were killed and about 50 wounded in the strikes and in cross-border shelling across the frontier in Kashmir that followed, while India says 13 of its civilians died and 59 were wounded.

The cross-border exchange of fire in Kashmir tapered off slightly overnight, Indian officials said. Reuters
