An explosion flattened a house allegedly being used by fighters in Pakistan's financial capital Karachi on Friday, with seven people killed when bomb-making materials detonated accidentally, police said.
Guns, grenades and suicide vests were recovered from the house in the poor Baldia Town neighbourhood, while bodies were buried under the rubble as bomb disposal experts worked cautiously to clear the site.
It looks like the people inside the house were "some militants," said area police official Ghulam Hussain Korai.
The blast brought down the house, and weapons were found in the rubble, Karachi police chief Waseem Ahmed told Reuters.
"Police have recovered one Kalashnikov rifle and two hand grenades," Ahmed told Reuters. "We have also taken into custody two suspects who were injured in the blast."
Baldia Town mayor Kamran Akhtar said the seven dead were in the rented house at the time of the attack, with no passers-by caught in the blast.
Karachi is home to Pakistan's main stock market, the central bank and its two main ports.
As the country's industrial hub, the city generates 68 percent of government revenue and 25 percent of gross domestic product.
