Bangladesh’s International Crimes Tribunal on Thursday issued an arrest warrant for former Prime Minister Sheikh Hasina, citing her alleged involvement in mass killings during violent protests that erupted earlier this year.

The protests, which began as a student-led movement against public sector job quotas, escalated into some of the deadliest unrest since the country’s independence in 1971, resulting in over 700 deaths and numerous injuries, Reuters reported.

The violence ultimately forced Hasina to flee to India on Aug. 5 and an interim government led by Nobel Peace Prize laureate Muhammad Yunus took charge.

The tribunal’s proceedings, presided over by Justice Golam Mortuza Majumdar, saw prosecutors request arrest warrants for 50 individuals, including Hasina.

“I appealed to the court that if the accused, who are extremely influential, are not arrested, it will be impossible to conduct the investigation," chief prosecutor Mohammad Tajul Islam said.

To date, more than 60 complaints have been filed against Hasina and other leaders of her Awami League party, alleging enforced disappearances, murder, and mass killings.

Party leaders from the Awami League were not immediately available for comment, as many senior members have either been arrested or have gone into hiding.

However, Hasina’s son, Sajeeb Wazed, told Reuters last month that his mother was ready to face trial in Bangladesh, adding: “My mother has done nothing wrong.”

Islamist militants stormed a northwestern Pakistani district police office on Monday, killing three policemen and a civilian before police shot and killed all five attackers, Reuters reported.

Provincial police chief Akhtar Hayat told Reuters that the attack on the complex, which houses both the district police headquarters and a residential complex, lasted for hours before all the five suicide bombers were killed.

The attackers killed three police officers and a civilian employed at the complex, he said.

The incident occurred in district Bannu, which borders the restive North Waziristan tribal region on the Pakistan-Afghanistan border, read the report.

Islamist militant group Tehreek-e-Taliban Pakistan (TTP) claimed responsibility for the attack, a spokesperson for the group said.

Bannu is about 350 km (217 miles) from Pakistan's capital Islamabad, which is under strict security lockdown due to the arrival of Chinese Premier Li Qiang on Monday ahead of a regional leaders' meeting this week.

Pakistan's capital was under strict security lockdown as Chinese Premier Li Qiang landed in the city on Monday ahead of a heads-of-government gathering of the Shanghai Cooperation Organisation this week, Reuters reported.

Li's visit is the first by a Chinese premier to Pakistan in 11 years, Pakistan's Prime Minister's Office said. Pakistan's Prime Minister Shehbaz Sharif received Li at the airport.

The government has announced a three-day public holiday in Islamabad, with schools and businesses shut and large contingents of police and paramilitary forces deployed.

Pakistan army troops will be responsible for the security of the capital's Red Zone, the location of the parliament and a diplomatic enclave and where most of the meetings will take place, according to the interior ministry.

The threat alert has been high in the South Asian nation ahead of the SCO summit, especially after the killing of two Chinese engineers and shooting to death of 21 miners, read the report.

Tensions have mounted after jailed former Prime Minister Imran Khan called for a protest on Oct. 15 to press for his release and agitate against the coalition government, following violent clashes between his party loyalists and security forces.

Islamabad has sought to curb all movement of Chinese nationals in the city, citing fears they could be targets for violence from separatist militants.

The 23rd meeting of the SCO, which comprises nine full members including China, India, Iran and Russia, is scheduled for Tuesday and Wednesday in Islamabad.

As well as attending the SCO summit, Prime Minister Li is also undertaking a four-day bilateral visit to Pakistan from Monday to Thursday, accompanied by senior officials, Pakistan's foreign office said.

Li and Pakistani Prime Minister Shehbaz Sharif will lead their respective delegations to discuss economic and trade ties and cooperation under the China Pakistan Economic Corridor (CPEC), a $65 billion investment in the South Asian country under Chinese President Xi Jinping's Belt and Road Initiative.

Li will also inaugurate the CPEC funded Gwadar International Airport in restive southwestern Balochistan province, which borders Afghanistan and Iran, Pakistan's prime minister's office said.

The SCO participants will be represented by the prime ministers of China, Russia, Belarus, Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan as well as the first vice president of Iran and external affairs minister of India, the foreign office said.
