One person has been killed and at least six others wounded in an ongoing mutiny at a border guards HQ in Dhaka, Bangladesh, reports say.
One person has been killed and a number of people wounded in a mutiny at the border guards headquarters in Bangladesh's capital, Dhaka.
Negotiators have entered the barracks complex, but it is still not clear what the soldiers' demands are.
Negotiations have now started between the government and representatives of the paramilitary troops who mutinied.
Heavy fighting started at 0330 GMT and is still going on. An army helicopter patrolling above the barracks was fired at, and mortar rounds were also fired.
The mutiny is reportedly over pay, conditions and career advancement.
It comes a day after PM Sheikh Hasina visited the HQ to hand out medals.

There is a heavy army and police presence at the scene, in the centre of the capital. The streets have been cleared and shops have been closed.
The barracks holds 3,000-4,000 troops.
One soldier was heard addressing the mutineers by megaphone: "Brothers, let's stay together. The army is trying to come in, and we will stop them by any means."
Some reports said the mutineers had taken officers hostage.
Sheikh Hasina visited the barracks on Tuesday A large plume of smoke can be seen rising above a conference room inside the barracks in the Pilkhana area of Dhaka, our correspondent says.
One of the mutineers called the BBC and said the action was because of discrimination against BDR troops by the regular army, who make up the officers.
Local media reports say that the mutineers have locked up their officers there.
The mutineers say the BDR rank and file were denied permission to speak to Sheikh Hasina when she visited.
Asifur Rahman was on his way home from university when he got caught up in the violence.
One BDR member was heard addressing the mutineers by megaphone: "Brothers, let's stay together. The army is trying to come in, and we will stop them by any means."
There were reports that some of the paramilitaries also stormed out of the complex and seized the nearby shopping centre.
Representatives of the mutineers have now been given safe passage, escorted by two MPs, to the office of Sheikh Hasina and talks are under way.
The Bangladesh army earlier issued a statement calling on the renegade troops to "surrender and go back to the barracks".
Sheikh Hasina visited the barracks on Tuesday "Any soldiers who fail to give up arms after this announcement will be prosecuted," the statement said.
One mutineer told local television the action would not end unless the government "declares a general amnesty, meets our demands and withdraws the army from outside the compound".
The BBC's Mark Dummett says there is still intermittent fire in the area and that streets and shops have been closed near the site in the Pilkhana area of Dhaka.
Our correspondent says there is no indication that this is a coup.
However, security has been tightened at other BDR barracks around the country and India says it has put its own Border Security Force on alert.
One witness, Asifur Rahman, was on his way home from university when he got caught up in the violence.
"It was pretty bad and everyone was running, trying to get away," he told the BBC.
