Pakistan has failed to prove the alleged "involvement" of India in a case related to the November 2018 attack on the Chinese consulate in Karachi, in which four people were killed.

The Anti-terrorism Court (ATC) Pakistan on May 26 expressed displeasure at the failure of the prosecution to present witnesses against suspected members of the ethnic insurgent group Baloch Liberation Army (BLA) for facilitating the attack on the Chinese consulate in Karachi.

According to the charge sheet registered, the attack was carried out by the BLA in connivance with India's Research and Analysis Wing to harm the relations between Pakistan and China and disrupt the China-Pakistan Economic Corridor project, reported The News International.

The ATC-VII judge ordered the investigation officer (IO) of the case to ensure presence of the complainant in the courtroom on July 7 since he had not appeared on four last hearings despite being issued summons.

The court had in January charged five people for providing weapons, hideouts and cash to the perpetrators. Three heavily armed militants had carried out the attack on the Chinese consulate located in Clifton on November 23, 2018.

Four people, including security personnel and visa seekers, were killed in the attack. The attackers, later identified as Abdul Razzaq, Raees Baloch and Azal Baloch, were also killed in their fight with police. A large number of weapons, ammunition and explosives were found on them.

The accused - Ahmed Hasnain, Muhammad Aslam, Nadir Khan, Ali Ahmed and Abdul Latif - were arrested by the Counter-Terrorism Department for allegedly facilitating the attack. According to the IO, Latif and Aslam had confessed to the crime before a judicial magistrate a week after their arrest.

Besides the indicted suspects, the police had also booked BLA chief Hyrbyair Marri and other leaders Kareem Marri, Bashir Zaib, Aslam Baloch, Noor Bakhsh Mengal, Rehman Gul, Nisar, Gaindi, Sheikhu Sharif, Hamal, Agha Sher Dil and Munshi. All of them have been declared proclaimed offenders in the case.

Issuing perpetual warrants of arrest for the absconders, the ATC earlier ordered police to approach Interpol for the arrest of Hyrbyair who is living in exile and who allegedly masterminded the attack from a foreign country.

The charge sheet said the terrorists stormed the consulate building and started firing and throwing hand grenades, which killed assistant sub-inspector Ashraf Dawood and police constable Muhammad Amir who were performing security duty at the first check post. A visa seeker, Tahir Shah, and his father, Niaz Ahmed, were also killed by the attackers, it reported further.
