Hundreds of people were injured Sunday in clashes between police and thousands of protesters, who are demanding Minister Nawaz Sharif's resignation over what they say were rigged elections in 2013, NBC News reported. The protesters, who are also angry over police brutality and the killing of 14 demonstrators back in June, marched to the prime minister's home, where they were met with rubber bullets and tear gas. Police said they fought back after some protesters threw rocks and fired weapons at them — but a senior military source said the protesters were weaponless.
