Police in Indonesia are trying to find out who was behind two bomb blasts in Jakarta that killed nine people.
Two big hotels were targeted in the city, and more than 50 people were injured in the explosions.
One of the hotels - the Ritz Carlton - was getting ready to welcome the Manchester United football team.
They were scheduled to arrive on Saturday ahead of a friendly against an Indonesia Super League XI on 20 July. That match has now been cancelled.
A United spokesperson said the club "cannot fulfil the fixture in Jakarta".

It's not thought any British people were among those killed.
Police think the explosions were caused by suicide bombers and while they suspect a particular group planned them, they aren't sure at the moment.
The first two blasts happened at about 7.30am local time.
"I heard two sounds like 'boom, boom' coming from the Marriott and the Ritz-Carlton. Then I saw people running out," security guard Eko Susanto told reporters.
