Brits are among the thousands injured in the devastating Beirut explosion.
At least 100 people have been killed and 4,000 wounded in the blast on the Lebanon capital's port, believed to have been caused by a vast store of ammonium nitrate that had been lying unsecured in a warehouse for years.
Some of those who sustained injuries are Britons, Sky News reports.
A Foreign Office spokesperson has confirmed that a small number of staff at the UK embassy in Beirut received non-life threatening injuries in the explosion.
No embassy staff were killed, and it remains to be seen whether the death toll includes any Brits.
Beirut governor Marwan Abboud has been quoted as saying half the city has been damaged in the blast, and the cost of the damage will likely exceed $3 billion (£760 million).
He said approximately 300,000 people have been made homeless by the disaster — almost the entire population of the city centre.
Yesterday Prime Minister Boris Johnson tweeted: "The pictures and videos from Beirut tonight are shocking. All of my thoughts and prayers are with those caught up in this terrible incident.
"The UK is ready to provide support in any way we can, including to those British nationals affected."
Also among the injured are international troops who were station in Lebanon while serving in the United Nations Interim Force, a UN-NATO peacekeeping force that has maintained a presence in the country since 1978.
The Bangladesh military says at least 21 members of its Navy were wounded in the blast, with one having been admitted to the American University of Beirut Medical Centre in critical condition.
Italy defence minister has also claimed one of the country's soldiers has been injured.
The cause of the explosion remains unconfirmed, although authorities have blamed an enormous supply of ammonium nitrate for the explosion that sent a shockwave through the city.
In a televised speech, Prime Minister Hassan Diab implied someone was to blame for the blast at the "dangerous warehouse", adding "those responsible will pay the price".
President Michel Aoun said that 2,750 tonnes of ammonium nitrate, used in fertilisers and bombs, had been stored for six years at the port without safety measures, which he called "unacceptable".
