SYDNEY (Reuters) - Security has been tightened at Australian airports after police foiled "Islamic-inspired" plans for a bomb attack on an aircraft during counter-terrorism raids in which four men were arrested, the Australian Federal Police (AFP) said on Sunday.

The increased security presence caused minor delays for some air transport operators on Sunday and authorities warned travellers to prepare for potentially more significant disruptions as traffic picked up during the week.
