Four people were killed yesterday when gunmen armed with hand grenades and a suicide vest stormed the Chinese consulate in the Pakistani city of Karachi, officials said, with the attack claimed by a separatist group which branded Beijing "an oppressor".
Separately, a suicide bomb attack at a crowded marketplace in northwestern Orakzai, Peshawar killed at least 31 people and wounded 50 yesterday, local media reported.
Pakistani authorities said security forces had secured the area surrounding the consulate after the attack, the latest assault on Chinese nationals in the country, where Beijing has poured billions of dollars into one of the largest projects in its massive Belt and Road programme.
China "strongly condemned" the attack and asked Pakistan to take measures to ensure the safety of Chinese citizens and institutions in the country, as well as the China-Pakistan Economic Corridor (CPEC) mega-project.
Three gunmen tried to enter the consulate in the southern port city, but were intercepted by guards at a checkpoint, Karachi police chief Ameer Sheikh told AFP.
"They were holding Kalashnikovs. First, they hurled a small (grenade) and then started firing," said Allah Bakhsh, a guard at a nearby house who witnessed the attack.
Police officials said two of their personnel were killed, along with a father and son from Quetta, the capital of Balochistan, who were seeking Chinese visas and were caught in the crossfire.
At least one of the attackers was wearing a suicide vest which did not detonate, another senior police official said.
Foreign Minister Shah Mehmood Qureshi told reporters in Islamabad that "all the terrorists have been eliminated", and that all 21 staff at the consulate during the attack had been taken to a safe location.
CHINA IS AN 'OPPRESSOR'
The attack was claimed by a separatist militant group from Pakistan's southwestern province of Balochistan, which is at the centre of the China-Pakistan Economic Corridor, the major Chinese project in the country.
"We have been seeing the Chinese as an oppressor, along with Pakistani forces," the spokesman for the Balochistan Liberation Army (BLA), Geand Baloch, told AFP by telephone from an undisclosed location, adding they were "destroying the future of Balochistan".
The BLA later emailed a statement to media in which it said the attack was "aimed at making it clear that China's military expansionism on Baloch soil will not be tolerated".
It warned the Chinese to leave or "be prepared for continued attacks".
The group is just one of the militant outfits operating in Balochistan, Pakistan's largest and poorest province, which is rife with ethnic, sectarian and separatist insurgencies.
Prime Minister Imran Khan said yesterday's attack would not undermine the Pakistan-China relationship, which he described as "mightier than Himalayas and deeper than Arabian Sea".
India also condemned the attack, saying there was no justification for such violence.
Also yesterday a bomb hidden in a carton of vegetables killed at least 31 people at a marketplace in Pakistan's northwestern tribal region. Dozens more people were wounded, with fears the toll could rise.
The attack took place during the regular Friday bazaar in Kalaya, a town in a Shia-dominated area of Orakzai tribal district in Peshawar, senior local official Khalid Iqbal told AFP.
"According to our initial investigation, it was an improvised explosive device hidden in a carton of vegetables," he said.
Senior official Ameen Ullah said 31 people had been killed, including 22 Shia Muslims.
China, one of Pakistan's closest allies, has poured billions into the South Asian country in recent years as part of CPEC, a massive infrastructure project that seeks to connect its western province Xinjiang with the Arabian Sea port of Gwadar in Balochistan.
The project is one of the largest in Beijing's "One Belt One Road" initiative, comprising a network of roads and sea routes involving 65 countries.
Pakistan sees the project as a "gamechanger", but it presents an enormous challenge in a country plagued by weak institutions, endemic corruption and a range of insurgencies in areas slated to host the corridor.
The subject of economic dividends from CPEC is extremely sensitive in some of those areas -- particularly in Balochistan.
Since the beginning of the project militants have repeatedly attacked construction sites, blowing up numerous gas pipelines and trains, and targeted Chinese workers.
In August this year three Chinese nationals were among six wounded in a suicide attack on a bus transporting Chinese engineers working in Balochistan, in an attack that was also claimed by the BLA.
