Nov. 15 (UPI) -- Argentina, which hosts the G20 meeting later this month, cracked down Thursday on anarchist groups blamed for placing bombs at the home of a federal judge and on the gravestone of a former police chief.

Patricia Bullrich, minister of internal security, said there's a connection between attacks at the grave of former police chief Ramon Falcon and the home of judge Claudio Bonadio, Radio Mitre reported.


"We will not accept this type of violent situations from those that committed this type of attacks," said Argentine President Mauricio Macri, state news agency Telam reported Thursday.

Macri vowed to "uproot" the violence and said those behind Wednesday's bombings "will pay the consequences." He added that security for the G20 meeting is guaranteed "through a professional, serious plan."

Bullrich said a couple was detained for the cemetery bombing and a 26-year old man for throwing the explosive against the judge's house, Mitre reported.

As of Thursday morning, 13 people have been arrested, Bullrich added.

The Clarin newspaper reported the woman held for the cemetery attack is Anahi Salcedo, 33, and she lost three fingers. She went to the cemetery in a wig and a wheelchair with Hugo Rodriguez, 38, the report said.

Their arrest occurred as the authorities arrived at the cemetery after reports of an explosion and injuries to a wheelchair-bound woman. She also received serious burns to the head and was hospitalized in intensive care, Clarin reported. Postings attributed to her online show anarchic symbols and invitations to "anarchic cinema."

The bomb at the judge's home did not explode and police later detonated it. The attacker was identified as Marco Viola. Police said the device was powerful and sophisticated.

Bonadio is also investigating a case involving former Argentine President Cristina Fernandez de Kirchner.

At the G20 summit, government leaders and central banks will meet on Nov. 30 and Dec. 1 to discuss sustainable development. The meetings will also be attended by heads of some of the leading financial international organizations.

The meeting of the group, established in 1999, will take place for the first time in South America.

Earlier this month, Britain advised citizens traveling to Argentina that "terrorists are very likely to try to carry out attacks."

The G20 consists of 20 nations, including Argentina, the United States, Britain, France, Russia and Germany.
