Kuwait City: Kuwaiti authorities are closely monitoring several relatives of Mohammad Emwazi who live and work in Kuwait where the alleged Daesh executioner was born, press reports said on Sunday.

A number of relatives of Emwazi, named as the militant who has beheaded at least five Western hostages, are working in Kuwait and like him hold British citizenship, Al Qabas newspaper reported.

“Security agencies have taken the necessary measures to monitor them round the clock,” the paper said, citing an “informed source.”

The daily did not say how many of Emwazi’s relatives are in Kuwait. Authorities have remained silent on the issue.

Al Rai newspaper cited security sources as saying that Emwazi’s father, Jasem Abdul Kareem, also a British national, is currently in Kuwait and is expected to be summoned by authorities.

Emwazi visited Kuwait several times, the last of them between January 18 and April 26, 2010, Al Qabas said.

He arrived using his British passport to obtain a Kuwaiti entry visa.

A year later, he was denied entry to Kuwait after his name came up during investigations into attacks in Britain, the newspaper said.

Emwazi’s visits to Kuwait were largely of a social nature. He was briefly engaged. Emwazi’s family is of Iraqi origin.

They applied for naturalisation but their names were removed from the list of prospective citizens because of allegations that they collaborated with the Iraqi army during its seven-month occupation of Kuwait in 1990-1991, Al Qabas said.

Emwazi was born in Kuwait but moved to London in the early 1990s when he was a child and attended school and university in the British capital.

The Daily Telegraph reported that he went to school with two other boys who went on to become militants — Choukri Ellekhlifi, who was killed fighting in Syria, and Mohammad Sakr, killed fighting in Somalia.

It was also reported that Emwazi had contacts with the men responsible for failed attacks on London’s public transport system in 2005, two weeks after suicide bombings killed 52 people in the British capital.

The revelations add to the pressure on the security and intelligence agencies to explain why they did not act on their suspicions about Emwazi before he travelled to Syria.
