MPs and representatives of Sydney's major religions will attend tomorrow's inter-faith gathering at NSW Parliament House to be addressed by prominent jurist John Dowd and relatives of imprisoned Baha'i leaders in Iran.

The closed trial of the seven leaders resumed in the Revolutionary Court, Tehran, on 7 February.

Baha'is throughout Australia will hold devotional gatherings this Sunday 7 February to pray for seven Baha'i leaders whose trial is scheduled to resume in Iran that day.

"The Australian Baha'i Community has grave fears for the safety of the seven", said spokesperson Tessa Scrine. 

The lawyers for seven imprisoned Baha'i leaders in Iran have been told by authorities that the next session of their clients' trial is scheduled for 7 February.

The world will be closely watching the next session, a Baha'i spokesperson said today.
