Rescuers in Northern Pakistan have dug desperately through the remains of a minister’s house flattened by a suicide bomb attack. At least nine people are known to have died and up to 20 are buried under the rubble, Euronews reported. The roof caved in as Punjab Province Home Minister Shuja Khanzada met with supporters inside. He was one of those killed. Punjab is Pakistan’s biggest and wealthiest province. It is the political heartland of Prime Minister Nawaz Sharif. A Taliban-affiliated militant group, Lashkar-e-Islam, claimed responsibility for the attack, saying it was in retaliation for military operations against them.
