The Greek authorities should immediately review their policy of locking up irregular migrants and asylum-seekers, including many unaccompanied children, Amnesty International said in a new report on Tuesday.

Greece: Irregular migrants and asylum-seekers routinely detained in substandard conditions, documents their treatment, many of whom are held in poor conditions in borderguard stations and immigration detention centres with no or limited access to legal, social and medical aid.

Migrants continue to endure multiple forms of discrimination, exploitation and other violations of human rights, a senior United Nations official has said, calling for their protection and social inclusion in communities where they live.

HIROSHIMA, Japan — Six young Chinese women arrived in this historic city three summers ago, among the tens of thousands of apprentices brought to Japan each year on the promise of job training, good pay and a chance at a better life back home.

Seven other Latin American countries want to join Mexico in supporting a lawsuit challenging Arizona's immigration enforcement law.

Bolivia, Colombia, El Salvador, Guatemala, Nicaragua, Paraguay and Peru filed separate, nearly identical motions to join Mexico's legal brief supporting the lawsuit filed by U.S. civil rights and other advocacy groups.

A federal judge formally accepted Mexico's filing July 1 but did not immediately rule on the latest motions filed late last week.
