Iraqi diplomat's sons investigated in Portugal over assault

Portugal's foreign minister says the alleged beating of a 15-year-old Portuguese boy by the teenage sons of Iraq's ambassador to Lisbon is "extremely serious."

Foreign Minister Augusto Santos Silva says Portugal may ask for the diplomatic immunity of the diplomat's 17-year-old twin sons to be lifted if prosecutors decide to bring charges.

The Portuguese boy was reportedly still in a coma Tuesday after last week's night-time attack in a street of Ponte de Sor, a rural town about 180 kilometers (110 miles) northeast of the capital Lisbon. One of the diplomat's sons was studying at a flying school there.

Local emergency services said the boy had multiple facial fractures and was evacuated to a Lisbon hospital by helicopter. The incident has brought an outcry in Portugal.
