MH17 Rosmah Mansor has sent word to Russian President Vladimir Putin to call her husband, Prime Minister Najib Abdul Razak, over the MH17 tragedy.

According to a brief report in Sin Chew Daily website, Rosmah said she had asked someone, who is close to her as well as Putin, to convey the message.

However, there is no mention as to who this person is.

The report stated that Rosmah is hoping Putin would take the initiative to call Najib and explain the issue in order to calm down Malaysians, who are enraged over the incident.

Sin Chew also did not state where she had made the remarks.

Rosmah was present at a Wanita Umno function in Kuala Lumpur earlier but Bernama , which reported on the event, made no mention of her commenting on the ill-fated plane .

However, the report was removed from Sin Chew website later in the day.

Meanwhile, Najib, who was slated to hold a special address on MH17 at 8pm, later tweeted that it was "postponed for several hours".

Najib, who attended an iftar function with bloggers and online media practitioners, only managed to eat a date before he received calls from world leaders regarding the tragedy.

According to the news agency, when the call for prayers resounded at the mosque in Angkasapuri, the prime minister received a call from United Nations (UN) secretary-general Ban Ki-moon.

Najib was seen talking for more than 10 minutes over the phone on the incident before performing his prayers at the mosque.

Upon completing Maghrib prayers, Najib received a call from Putin.

MH17, which was en route to Kuala Lumpur from Amsterdam, is believed to have been shot down as it flew over Ukraine, which is roiling in conflict.

Ukraine has blamed the Russian-backed separatist rebels for the missile attack while Russia has pointed the finger at the former.

All 298 passengers and crew, including 44 Malaysians, are believed to have perished after the aircraft burst into flames.

Early this morning, Najib demanded " swift justice " if it is proven that the Boeing 777 had been shot down.
