In a statement, Pakistan's Ambassador to Lebanon Najeeb Durrani said that the teenage boy's father — identified as Sajid — and his sister are currently in intensive care at a hospital. He said that the 14-year-old boy’s mother and grandmother were also wounded in the explosion.
The envoy said that the Pakistani family was residing near the port in an apartment. Durrani said that the Pakistani embassy is trying its best to facilitate the affected family.
At least 4,000 people were also wounded by Tuesday's explosion, while dozens of people were still missing as rescue efforts continued, the health minister of the country told reporters on Wednesday.
Rescuers worked through the night into Wednesday after the explosion ripped through Beirut's port, wrecking buildings across the Lebanese capital.
The blast sent an enormous orange fireball into the sky, immediately followed by a tornado-like shockwave that flattened the port and shattered windows across the city.
The explosions — which were heard in Nicosia, 240 kilometres (150 miles) away in Cyprus — were logged by seismologists, registering as the equivalent of a 3.3-magnitude earthquake.
