Pakistan Tehrik-i-Insaaf (PTI) chief Imran Khan hasn’t received any notice from Muttahida Qaumi Movement (MQM) on account of his remarks against Altaf Hussain, Khan’s sister Aleema Khan said.

Earlier, MQM had announced its decision to sue the PTI chief for Rs 50 billion for accusing Altaf Hussain over the killing of PTI leader Zahra Shahid Hussain.

In a video message released on Sunday from the Shaukat Khanum Memorial Hospital where Imran is recovering from injuries suffered in an accident during an election rally, the PTI chief said he held the MQM responsible for the killing of Zahra Shahid. Imran had moreover termed the incident part of the MQM’s policy to control the city by spreading fear.

Imran, in a tweet, also held the British government responsible for the ‘murder’ of Zahra Shahid saying he had warned them about British citizen (Altaf Hussain) after his open threats to PTI workers’ lives.

Zahra Shahid Hussain was the former president of the women's wing of the party’s Sindh chapter and was also one of the founding members of PTI. She was gunned down outside her residence on Saturday night, hours before re-polling in 43 polling stations of NA-250 was scheduled to begin.

Speaking to media representatives today, Aleema said PTI workers were receiving threats, adding that the British government had finally made contact with Imran on the matter.

In related news, PTI workers were holding a protest against the killing of Zahra Shahid at the Peshawar Press Club.

Moreover, PTI workers in Karachi were scheduled to hold demonstrations near the mausoleum of Muhammad Ali Jinnah later today.
