The Malaysian government has begun holding seminars aiming to help teachers and parents spot signs of homosexuality in children, underscoring a rise in religious conservatism in the country.

So far, the Teachers Foundation of Malaysia has organised 10 seminars across the country. Attendance at the last event on Wednesday reached 1,500 people, a spokesman for the organisation said.

"It is a multi-religious and multicultural [event], after all, all religions are basically against that type of behaviour," said the official.

The federal government said in March that it is working to curb the "problem" of homosexuality, especially among Muslims who make up over 60% of Malaysia's population of 29 million people.

According to a handout issued at a recent seminar, signs of homosexuality in boys may include preferences for tight, light-coloured clothes and large handbags, local media reported.

For girls, the details were less clear. Girls with lesbian tendencies have no affection for men and like to hang out and sleep in the company of women, the reports said.

Malaysia frowns on oral and gay sex, describing them as against the order of nature. Under civil law, 'offenders', both male and female, can be jailed for up to 20 years, caned or fined.
