At least six dead as violent nationwide protests erupt across Pakistan following former Pakistan prime minister Imran Khan's arrest.
On Wednesday, he was remanded in custody for eight days by an anti-graft court.
Imran was arrested on Tuesday during a routine hearing in the capital Islamabad and whisked away to an unknown location overnight before appearing behind closed doors in a specially convened court at police headquarters.
The drama follows months of political crisis during which Imran, who was ousted in April last year, has waged an unprecedented campaign against the country's powerful military.
"If they think that the arrest of Imran Khan will demoralize us, then they are hugely mistaken," said Niaz Ali in Peshawar, where several monuments and government buildings have been torched.
"We stand with Imran Khan and will support him till death."
Ali Bukhari, a lawyer for Imran Khan, told AFP by phone that the court had approved eight days of physical remand of Imran demanded by the country's top graft agency.
Afzal Marwat, another of Imran's lawyers, earlier said he was in "good spirits" but had complained of being hit on the back of the head and leg by paramilitary forces who arrested him.
The former cricketing superstar, who remains wildly popular, has previously said the dozens of cases brought against him are part of an effort by the struggling government and military establishment to prevent him from returning to power.
His arrest has brought thousands of his supporters to the streets in cities across the country, where police have attempted to quell crowds with tear gas.
At least six people have died in protest-related incidents, police and hospitals reported, including one person who died from smoke inhalation after a multi-storey building was set on fire in Lahore.
Internet cut, exams cancelled
The interior ministry had ordered mobile internet services cut and restricted access to social media sites Twitter, Facebook and YouTube, the country's communications agency said.
Authorities have ordered schools closed across the nation –- with end of year exams cancelled for students.
Hundreds of police officers have been injured across the country, while in Pakistan's most populous province of Punjab nearly 1,000 people have been arrested and the army ordered to deploy to keep peace.
"At a time when we are already struggling to feed our children, further uncertainty has been created," Farooq Bhatti, a van driver, told AFP in Rawalpindi.
Some protesters took out their wrath on the military, torching the residence of the corps commander in Lahore and gathering outside the entrance to the army's general headquarters in the garrison city of Rawalpindi and pelting it with stones.
On Wednesday, the military's media wing released a statement warning of a "strong reaction" against those who attack military and state installations."
