Police are still waiting for the official confirmation on the identities of two suicide bombers in Iraq and Syria, alleged to be Malaysians.

Inspector-General of Police (IGP) Tan Sri Khalid Abu Bakar said police were worried that there were parties using the identity of Malaysians to carry out the acts.

"...there is a 45 per cent chance our people may be involved (in the suicide bombings) but I want to wait for the report first to confirm.

"Police have their own ways to identify them, we will review once we obtained the official confirmation," he said.

He was speaking to reporters after attending the monthly assembly of all Bukit Aman (Federal Police) departments at its Complex 3 compound here today.

Khalid had said earlier that there were Malaysians who had chosen to be suicide bombers on their own accord.

According to a news report yesterday, two Malaysians blew themselves up causing the death of more than 30 people in Syria and Iraq in two incidents last week.

Mohd Amirul Ahmad Rahim, 26, who hailed from Terengganu, triggered a bomb strapped to himself in a car during a battle at the IS terrorist stronghold at Raqqa, Syria on Dec 29, the report said.

Mohamad Syazwan Mohd Salim, 31, who carried out the mission on Jan 3 was one of seven suicide bombers to infiltrate a police training centre at the Speicher military base, about 160km north of Baghdad, Iraq.
