After Lahore, reports emerge of explosion in Karachi’s Sharafi Goth

Pakistan: An explosion was reportedly heard near Sharafi Goth in Karachi on Thursday. The Karachi reports comes close on the heels of a similar episode in Lahore. 
The developments follows Indian missile strikes on Pakistani locations. Tensions between the two countries have spiked since April 22, when terrorists killed 26 people, mostly Hindu tourists, in Pahalgam. India accused Pakistan of backing the terrorists who carried out the attack, something Islamabad has denied.
What Pakistan says

Pakistan's army said Thursday it shot down 25 Indian drones

Pakistan's military said in a statement that it had "so far shot down 25 Israeli-made Harop drones" at multiple location across the country.

"Last night, India showed another act of aggression by sending drones to multiple locations," Pakistan's military spokesman Ahmed Sharif Chaudhry said from the army's headquarters in Rawalpindi, where a drone was downed.

"One managed to engage in a military target near Lahore," he said, adding that four troops in the city were injured.

He earlier said the operation was ongoing.

One civilian was killed and another injured in Sindh as a result of the drone incidents.

Crowds gathered at crash sites, some close to army installations, to gaze at the debris.

Blasts could be heard across Lahore.

The Civil Aviation Authority said Karachi airport was closed until 6 pm (1300 GMT), while Islamabad and Lahore were briefly shut "for operational reasons".

Earlier, Pakistan's military also said five Indian jets had been downed across the border, but New Delhi has not responded to the claims.

An Indian senior security source, who asked not to be named, said three of its fighter jets had crashed on home territory.
