Iran has summoned the United Arab Emirates envoy to Tehran over the arrest of nine Iranian teachers who were working in the Gulf federation.

Iran's semi-official ISNA news agency reported Sunday that the Foreign Ministry had summoned the UAE's charge d'affaires over the Oct. 7 arrests.

Iran's semi-official Fars news agency says the Iranian teachers appear to have been arrested due to visa issues. Fars quotes Khalilollah Babalou, an Education Ministry official, as saying the teachers may be released Monday.

Emirati officials had no immediate comment.
