KARACHI -- Pakistani police in armored vehicles descended on former Prime Minister Imran Khan's home in Lahore on Tuesday, apparently intending to arrest him, in a sharp escalation of the country's political tensions.
Khan was facing new arrest warrants as he continues his raucous campaign to force elections, nearly a year after he was ousted in a no-confidence vote. On Twitter, his Pakistan Tehreek-e-Insaf (PTI) party urged supporters to hurry to the residence at Zaman Park but to "stay calm." The situation quickly deteriorated as the growing crowd slowed the officers' advance.
