Police in the Brazilian city of Rio de Janeiro have deployed armoured vehicles in a shanty town as they continue operations to stem a wave of violence.
Six vehicles transporting heavily armed police rolled into Vila Cruzeiro, in the north of the city.
Clashes in Rio since the weekend have left more than 20 people dead.
“We’re acting to reassure the population”
Col Alvaro Garcia Military police commander
Drug gangs have been burning vehicles and opening fire in an attempt to halt police operations aimed at pacifying the favelas, officials say.
Some 150 members of the Special Police Operations Battalion (Bope) and the military police force, backed up by the navy’s armoured vehicles, began deploying in Vila Cruzeiro at lunchtime on Thursday, Brazilian media reported.
“The aim of the operation is to arrest the people behind the attacks in the city,” the head of Rio’s military police, Col Alvaro Garcia, said.
“We’re acting to reassure the population.”
Staffing was also stepped up at a nearby hospital ahead of the operation.
Violence has steadily increased since the weekend
Officials said that drug traffickers had regrouped in Vila Cruzeiro after being expelled from other shanty towns in the city.
At least 23 people have been killed since the weekend when the latest wave of violence erupted.
Heavily armed men have been stopping cars and buses, robbing passengers and setting vehicles alight.
Some 17,500 police officers have been deployed to try to stop the violence.
Rio’s favelas have for years been controlled by heavily armed drug trafficking gangs.
The city’s pacification programme is aimed at improving security and the rule of law in the run-up to the football World Cup in 2014 and the Olympic Games two years later.

Austerity measures are proving deeply unpopular
The euro has continued its slide against the dollar as investors digest the Irish Republic’s austerity plan.
The currency fell by almost half a cent to $1.3325, and has now fallen by more than three cents this week.
The four-year Irish plan is designed to save 15bn euros ($20bn; £13bn) through spending cuts and tax rises, but investors remain unconvinced.
The government is also negotiating a bail-out package with the European Union and International Monetary Fund.
This is expected to be worth about 85bn euros.
The austerity measures are designed to reduce the Republic’s budget deficit, which is the highest in the eurozone.
However, there are doubts about the Irish government’s growth estimates, which directly impact its deficit forecasts – many investors see them as overly-optimistic.
The government still expects the economy to average 2-2.5% growth in 2011, and 3.5-4.5% the year after, whereas rating agency Standard & Poor’s has said it expects virtually no growth over the next two years.
There also are also doubts about the whether the government will be able to push through its austerity measures when parliament votes on the budget on 7 December.
Compounding this uncertainty are fears that the Irish debt crisis will spread to other countries with high deficits, in particular Portugal and Spain.
All these factors are putting pressure on the euro.
In total, the spending cuts announced in the recovery plan will amount to 10bn euros, while tax rises will bring in a further 5bn euros.
The cuts include 2.8bn euros of savings in social welfare spending, 24,750 public sector jobs cuts and a 1 euro reduction in the minimum wage, to 7.65 euros an hour.
The tax rises include an extra 1.9bn euros from income tax changes, an increase in VAT from 21% to 22% in 2013, and to 24% in 2014, and a new “site value” property tax to raise 200 euros from most homeowners by 2014.
The government has already implemented 15bn euros of cuts in the last two years.
The measures have proved deeply unpopular with the electorate, and junior government partner, the Green Party, has called for a general election in January.
