Pakistan’s former prime minister, Imran Khan, has been shot and wounded in the leg in an attack on his protest march in the eastern city of Wazirabad.
It is unclear whether the politician was deliberately targeted as one of his senior aides claimed, or if he was hit by indiscriminate gunfire.
Members of his PTI party said another four people were hurt in the shooting.
Mr Khan, 70, was leading the march on the capital Islamabad to demand snap elections after he was ousted in April.
The former prime minister was seen being taken to a hospital in Lahore. A party spokesman said he had been hit in the shin.
Another party leader, provincial health minister Yasmeen Rashid, said Mr Khan was in a stable condition.
An unnamed male suspect was later arrested, according to Pakistan’s Geo TV.
Footage from the scene shows a conscious Imran Khan with a bandage on his right leg being taken away in a vehicle after the shooting.
One video shows a PTI member with a bandage on his face and blood on his clothing, saying that people should pray for Mr Khan and all those injured.
Current Prime Minister Shehbaz Sharif condemned the shooting and ordered an immediate investigation.
Mr Khan has been leading a protest march – the second such rally this year – for the past seven days, calling for new elections.
The government has repeatedly said it will hold elections next year, as planned.
Last month, Pakistan’s election commission disqualified Mr Khan from holding public office in a case described by the former star cricketer as politically motived.
He had been accused of incorrectly declaring details of gifts from foreign dignitaries and proceeds from their alleged sale. The gifts included Rolex watches, a ring and a pair of cuff links.
Pakistan has a long history of deadly political violence.
In the most high-profile case, former Prime Minister Benazir Bhutto was assassinated at a public rally in 2007.
