Hundreds of people have been wounded in a powerful explosion that ripped through Lebanon's capital, Beirut, according to the country's health minister.
The massive explosion on Tuesday at Beirut's port caused widespread damage to buildings, shattering windows in different parts of the city. It sent shockwaves across the capital.
The cause of the explosion is not immediately clear.
Hamad Hassan, Lebanon's health minister, said hundreds were wounded in the explosion.
Video of the incident taken by Al Jazeera shows a large column of smoke billowing from an area of the port that houses large warehouses before a large orange explosion is seen and huge dome-shaped blast wave shoots into the air.
Glass storefronts and windowpanes across the city were shattered in the explosion, while videos and pictures shared on social media showed doors ripped from their hinges and ceilings filled with gaping holes.
This just happened a short while ago in downtown Beirut. Still trying to find out what is exactly happening.
The wave from the explosion caused extensive damage to buildings within a large radius of the blast site.
"I was kilometres away; the glass broke everywhere around me," said Al Jazeera's Zeina Khodr, reporting from Beirut.
"The explosion was felt across the city," she added. "There is chaos in the streets."
Local media showed people trapped beneath rubble. A witness described the first explosion as deafening. Video footage showed wrecked cars and blast-damaged buildings.
The latest reports come amid political tension in Lebanon, with street demonstrations against the government's handling the worst economic crisis since the 1975-1990 civil war.
There has also been tension on the border with Israel, which said last week that it had thwarted an attempt by Hezbollah to infiltrate Israeli territory.
