Former Prime Minister Imran Khan appeared before a magistrate in Islamabad on Wednesday, a day after he was arrested by police following a hearing in a separate case. The judge was asked to grant permission to detain the opposition leader for up to 14 days. 

Khan, who is still highly popular despite losing power last year, has become the seventh ex-Prime Minister to be arrested in the country. His detention has further exacerbated political unrest and led to violent protests across the country on Tuesday.

The clashes between Khan's supporters and police have led to at least two fatalities and several injuries in different parts of the country. One person was killed in the southwestern city of Quetta while the other was killed in northwestern Pakistan.

Additionally, dozens of people were injured in various parts of the country as a result of the violent protests. The situation has heightened political instability in Pakistan and created further unrest among the public.

Imran Khan's supporters had planned to hold a march to Islamabad, where the former Pakistani Prime Minister is being held in custody over corruption allegations.

This has raised concerns about potential clashes with security forces. Mobile data services were shut down in the country, and there were disruptions to social media platforms such as Twitter, YouTube, and Facebook.

Television coverage of the violence that occurred on Tuesday was limited. To prevent further clashes, authorities in three out of Pakistan's four provinces have implemented emergency orders prohibiting all gatherings.

Following Khan's arrest, his supporters took to the streets in protest, leading to clashes with police and the storming of military buildings in Lahore and Rawalpindi, according to witnesses and videos shared by his party.

This comes after the country's powerful military criticized Khan for repeatedly accusing a senior military officer of trying to engineer his assassination and the former armed forces chief of being behind his removal from power last year. In response to Khan's arrest, his Pakistan Tehreek-e-Insaf (PTI) party called for a nationwide "shutdown."

Khan's Pakistan Tehreek-e-Insaf (PTI) party called for a "shutdown" across the country in response to the military's rebuke. This led to clashes between Khan's supporters and police in many cities, and witnesses and videos shared by his party showed supporters storming military buildings in Lahore and Rawalpindi.

Khan's arrest came the day after he had accused a senior military officer of trying to engineer his assassination and had accused the former armed forces chief of being behind his removal from power last year. The police have said that a court hearing will take place at the police guest house where Khan is being held.

Meanwhile, mobile data services in Pakistan were shut down, and access to social media platforms like Twitter, YouTube and Facebook were disrupted.

The authorities in three out of four Pakistani provinces have imposed an emergency order banning all gatherings after Khan's supporters clashed with police.

Imran Khan, a former cricket star who became Pakistan's prime minister, was removed from power in April 2022 after a parliamentary no-confidence vote.

Despite being injured in a November attack on his convoy during a protest march calling for snap general elections, Khan has continued his campaign against his ouster.

His recent arrest and detention come at a time when Pakistan is grappling with a severe economic crisis, with record high inflation and sluggish growth, and has been waiting for months for an IMF bailout package.

The current corruption case against Khan is just one of over 100 cases registered against him since he was removed from power. If convicted, he could be barred from holding public office, and with a national election scheduled for November, this case could have significant implications for his political future.

Political infighting and instability are not uncommon in Pakistan, where no prime minister has ever completed a full term in office, and the military has ruled for nearly half of the country's history.
