Pakistan deploys army to quell protests following arrest of ex-PM Khan.

Pakistan's government has called in the army to help end deadly unrest following the arrest of former prime minister Imran Khan, warning protesters against any further attacks on state installations. At least five people have died in violence that has aggravated instability in the country. Khan was arrested in a land fraud case on Tuesday, prompting supporters to storm military buildings and ransack the residence of a top army general in Lahore. Another court indicted Khan earlier on Wednesday on charges of selling state gifts during his four years in power, a day after his arrest in the unrelated fraud case.
