Qatar has confirmed the arrest in the United Arab Emirates of two of its citizens, described as "spies" by Emirati media.
  
Hamad Ali al-Hamadi and Yousef Abdelsamad al-Mulla were arrested on June 27 at the Ghweifat border crossing between Saudi Arabia and the UAE, a Qatari foreign ministry spokesman said in a statement.
  
Their families had reported their arrests to Qatari authorities as the UAE had not officially informed Doha, according to the statement, published late on Wednesday by the official QNA news agency.
  
Qatar's ambassador to the UAE has been tasked with investigating the fate of the pair, the spokesman said, without giving further information.
  
Citing UAE sources, the Emirati Al-Khaleej newspaper, reported on Wednesday that authorities had arrested Qatari "spies", but gave the number as three.
