Bombs placed at the Jakarta Marriott and Ritz-Carlton, the hotel due to host the United squad for four days from Saturday, Jul 18 evening, exploded at 7.30 a.m. this morning, leaving nine dead and about 50 injured.
The team were due to arrive in Kuala Lumpur at 11.40 a.m. local time on Jul 17 prior to Saturday's tour opener against a Malaysian XI at the Bukit Jalil Stadium, reports The Telegraph.
The squad were then scheduled to fly to Jakarta on Saturday evening for a four night stay in the Indonesian capital, during which they were due to play an Indonesian Select team on Monday, Jul 20 evening.
United officials are now reviewing the team's security situation, but the trip to Jakarta now looks extremely unlikely as a result of the terrorist atrocities.
United, who have brought their first-team squad to the Far East, travel to all games with their own security team, which has accompanied the squad in the Far East.
