The government is stepping up security control at all entry points in the country, including airports, following the attacks in Paris last Friday.

Transport Minister Datuk Seri Liow Tiong Lai said the government was always on the alert against any threat to ensure the country remained safe and peaceful.

He described the Paris attacks as inhuman and an incident which had jeopardized harmony and well-being of the people.

"We have been very cautious in our safety measures, with all entry points, especially airport security, been tightened after many alerts.

"Actually we have been given the alert earlier. I think you also know the United States (US) also alerted us on the Jalan Alor (in Kuala Lumpur) case and the police have tracked down several activists in the country and some have been arrested.

"Malaysia has been on the high alert most of the time and we will continue to do so," he told a media conference after the ground-breaking ceremony for the construction of a Sekolah Menengah Jenis Kebangsaan Poi Lam here today.

According to reports, more than 100 people were killed in the Friday attacks by gunmen on restaurants, concert hall and a sports stadium in Paris.

PARIS ATTACKS: What we know so far

Liow said extremism is a world issue that has adverse effects on the country and its economy.

"I strongly condemned the attacks by the Islamic State (IS) which had claimed many lives," he added.

He thanked the police for maintaining peace and order in the country against all threats, including from the IS.

"We hope the people will remain united and together pray for peace in the country and the world, and for terrorist acts to end," he added.
