Police in Pakistan have arrested four men in connection with the bombing of the Islamabad Marriott Hotel on September 20.
The four men have not been charged in the case, but authorities say they will be held for at least seven days as police continue their investigation.
Police describe the men as being suspected of "indirect involvement" in the attack. The four appeared in court on Friday, hooded and handcuffed to policemen.
About 60 people were killed when a suicide bomber exploded a truck loaded with explosives just outside the main entrance to the hotel. Islamist militants are the main suspects in the attack.
Authorities say the four men detained were picked up under anti-terrorism statutes at various locations around Pakistan.
Some information for this report was provided by AFP, AP and Reuters.
