All available resources are being used in the search for missing British man Gareth Huntley, the Malaysian government has insisted.
Mr Huntley, 34, of Cricklewood, north London, has not been seen since going trekking on Tioman Island on Tuesday.
The search for him involves 100 people, including police officers and rescue teams, the Foreign Office said.
His mother, Janet Southwell, says she believes her son has been injured but is still alive.
