ISLAMABAD (AP) — Hundreds of people were injured as Pakistani police battled throngs of protesters demanding the resignation of Prime Minister Nawaz Sharif with tear gas, batons and rubber bullets outside the prime minister’s official residence and the adjacent parliament building.

After a night of clashes, protesters started regrouping at daybreak Sunday and made repeated attempts to make their way through heavy deployment of police and barricades to reach the premier’s residence. Police strengthened their lines and responded by lobbing tear gas canisters.
