Immigration officials say two Indian men who were force-fed through nasal tubes while on a hunger strike inside a Texas detention facility have been deported.

US Immigration and Customs Enforcement says the two detainees held at the El Paso Processing Center were deported to India on Friday.

ICE spokeswoman Leticia Zamarripa said on Monday there are nine detainees from India, Nigeria, Turkey, Bissau-Guinea, Pakistan and Croatia who have been refusing to eat in detention centres in the El Paso, Atlanta, San Diego, Miami and Seattle areas of responsibility.

Earlier this year, federal judges authorised nose-to-stomach force-feeding of nine detainees in El Paso. In response, the United Nations human rights office said the US could be violating the UN Convention Against Torture because it views force-feeding as potential "ill-treatment"
