Police on Wednesday successfully destroyed two suspected home-made bombs left at a car park near a popular shopping area in the Malaysian capital, a police official said.
The suspected explosives, contained in two plastic bottles, were seized at a car park at the Kuala Lumpur Convention Centre and successfully destroyed by police bomb experts, according to Kuala Lumpur Police Chief Tajudin Isa.
A civilian had informed security personnel about the presence of the suspicious package, Tajudin said.
Malaysian police have been on high alert since terrorist attacks in the Indonesian capital Jakarta in January killed several people, including the attackers.
On Tuesday, Interior Ministry officials revealed that local sympathizers of the extremist militia Islamic State plotted to kidnap Prime Minister Najib Razak and two other senior officials last year.
Federal Territories Minister Adnan Mansor warned in February that local Islamic State sympathizers were planning to launch terrorist attacks in public and tourist areas in Kuala Lumpur.
Malaysia, a predominantly Islamic South-East Asian country of over 30 million people, has not experienced a deadly terrorist attack.
Malaysian police have arrested more than 100 local Islamic State supporters since it began a crackdown on the militant group in early 2014.
The Interior Ministry estimates that more than 130 Malaysians have gone to Syria and Iraq to fight alongside Islamic State militants.
