one in the north related to the Matses or Northern Mayoruna, while the southern one related to Isconahua or Remo / Southern Mayoruna. In 1964, the Peruvian Air Force attacked some of the villages with Napalm, killing a large number of Indians. The tribes frequently criss-cross the Brazil-Peru border. In 2010, the Marubo living on the Brazilian side of the border claimed that more and more "Mayoruna" from Peru are crossing over to Brazil, in order to escape from loggers and missionaries. Violent clashes has occurred recently between the contacted Marubo and the uncontacted Mayoruna. Missionaries from the Summer Institute of Linguistics (SIL) are currently attempting to contact the uncontacted bands. [ 10 ] Isconahua (Iskobakebu) Located in North Ucayali, near the Brazil border. The villages are located in between Alto Rio Calleria, the Rio Utuquinia and the Rio Abujao. A reserve was established in 1998. In 1959, missionaries from the South American Mission attempted to contact one of the bands of Isconahua. This band numbered more than twenty people. The missionaries moved them to lower Rio Calleria, but almost all of them died of epidemics. The Isconahua calls themselves "Nucuini" and are thought to be the descendants of the once large Remo tribe. Most of the villages are covered by the Isconahua Territorial Reserve. The area is currently under extensive occupation by loggers, drug-traffickers and mining workers. [ 10 ] Isolados do Rio Calleria e Rio Maquia Locally known as Kapanawa. Speaks a Panoan language.
