An armed man demanding deposits frozen by his bank took an unspecified number of hostages on Thursday at the Federal Bank of Lebanon, a security source said and a Reuters witness said.
Lebanese banks have limited withdrawals of hard currency for most depositors during the country's three-year financial meltdown, which has left more than three-quarters of the population poor.
The man entered the Federal Bank of Lebanon branch in the Hamra neighbourhood in west Beirut just before noon on Thursday with a firearm, the security source told Reuters.
Some customers in the bank managed to flee before he shut the doors on the rest, said the source, who was not able to specify how many clients or employees were in the branch.
Two shots were subsequently fired, according to Lebanese media station Al-Jadeed.
A Reuters witness could see a bearded man in a black shirt behind the gated entrance to the bank speaking to several men in plainclothes on the outside.
"Let them give me back my money!" he was heard telling them.

Israel stepped up airstrikes on Syria, declaring the attacks a warning to the new rulers in Damascus as it accused their ally Turkey of trying to turn the country into a Turkish protectorate.
The Trump administration moved forward with the sale of more than 20,000 US-made assault rifles to Israel last month, according to a document seen by Reuters, pushing ahead with a sale that the administration of former president Joe Biden had delayed.
