Hundreds of thousands of Argentines have rallied in Buenos Aires to mark one month since the death of prosecutor Alberto Nisman.
The protest was called by federal prosecutors and attended by Alberto Nisman’s family and opposition politicians.
They defied torrential rain to demand justice for Alberto Nisman, who had been investigating the government.
Prosecutor Alberto Nisman was found dead in his apartment on 18 January.
It is still not clear whether he killed himself or was murdered.
Alberto Nisman was investigating Argentina’s deadliest terrorist attack, the 1994 bombing of the Amia Jewish centre.
The silent march was called by prosecutors demanding a full investigation.
Alberto Nisman’s ex-wife, federal judge Sandra Arroyo Salgado, and their two daughters joined the demonstration, which lasted nearly two hours.
Similar protests took place across the country.
Argentines living in Spain, France, Israel and other countries also gathered to demand justice for Alberto Nisman.
Officials have denounced the march as a political move to weaken the government.
Alberto Nisman was found with a bullet wound to the head and a gun was lying next to him.
Days earlier, he had published a 300-page report in which he accused President Cristina Fernandez de Kirchner and Foreign Minister Hector Timerman of covering up Iran’s alleged role in the bombing.
His body was found just hours before he was due to appear before a congressional committee to present more details of his allegations.
News of Alberto Nisman’s death and its timing led to speculation among some Argentines that the government may have played a role in it.
The government has strongly denied both allegations.
In an open letter published on her website, President Cristina Fernandez de Kirchner suggested rogue intelligence agents had fed Alberto Nisman false information in order to destabilize her government.
She also said she was convinced Alberto Nisman’s death was not suicide.
Days later, the president announced she planned to dissolve Argentina’s intelligence service, SI.
Critics said the move was aimed at diverting attention away from Alberto Nisman’s death.
A commuter train in Buenos Aires, Argentina, has crashed at the end of the line, leaving at least 35 people injured.
The train failed to stop as it arrived at Once station, crashing through the buffers and ending up wedged between the floor and ceiling of the platform.
The accident happened at the same station where 51 people were killed in a similar crash last year.
The cause of the accident remains unclear.
At least 35 people were injured Saturday morning when a train crashed in a Buenos Aires neighborhood
Saturday’s crash happened shortly after 07:00 local time.
The line from Moreno 25 miles west of Buenos Aires to Once station, operated by the Sarmiento train company, is normally a busy commuter line during the week, and its trains are usually packed with passengers.
Security Secretary Sergio Berni said some of those injured on Saturday had been waiting on the platform and were hurt by flying glass as the train’s windows shattered.
Jorge Ramirez, a chef who got on the train nine stations before the end of the line, told the AP news agency the accident was “a tragedy”.
“I saw people hurt, shouting, others thrown on the floor. The people in the first wagon ended up piled on top of each other,” he said.
After the 2012 crash, the authorities revoked a local company’s right to operate trains on the line and pledged to make new investments in safety.
Around 100 left-wing activists have protested by burning Union flags outside the British embassy in Buenos Aires on Friday to demand Argentina break off diplomatic relations with the UK over the Falkland Islands dispute.
Tension has been increasing ahead of the 30th anniversary of the Falklands War in April.
Argentina is demanding talks on its claim to sovereignty over the territory, which it calls Las Malvinas.
But the UK has reaffirmed that the Falklands will remain British for as long as its inhabitants want.
Around 100 left-wing activists have protested by burning Union flags outside the British embassy in Buenos Aires on Friday to demand Argentina break off diplomatic relations with the UK over the Falkland Islands dispute
The protest in Buenos Aires was organized by the Socialist Workers’ Movement (MST).
Activists carried banners reading “Government break off relations now,” and “English out of the Malvinas”.
“It is unacceptable that they send reinforcements and that the little prince (William) should come on manoeuvres,” said protest leader Wilma Ripoll of the MST.
Willma Ripoll added that her group was planning further protests before Prince William – who is the second in line to the British throne – arrives in the Falklands next month for a tour of duty as a helicopter rescue pilot.
The protest comes amid an escalating war of words between London and Buenos Aires over the Falklands.
Argentine leaders were particularly angered by comments made by the British Prime Minister David Cameron on Wednesday, when he said Argentina’s demand for sovereignty was “like colonialism” because it ignored the islanders’ right to self-determination.
He also said he had reviewed the Falklands’ military defenses and was prepared to send reinforcements if necessary.
Tension over the remote South Atlantic archipelago has been growing since 2010, when British companies began drilling for oil in waters off the Falklands.
Argentina has been rallying support for its claim from other Latin American nations, and President Cristina Fernandez has accused Britain of “arrogance” and “taking Argentine resources”.
Britain has held the islands since the 1830s, but Argentina insists it has a prior claim and in 1982 launched an invasion.
A British task force recaptured the islands in a short but bloody war in which 649 Argentine and 255 British servicemen were killed.
The US has called for dialogue between London and Buenos Aires to resolve the dispute.
“We recognize de facto UK administration of the islands, but take no position regarding sovereignty,” the State Department said.
