Malaysian police on Monday released computer generated photographs of two men suspected of gunning down Hamas drone engineer Fadi al-Batsh in Kuala Lumpur on Saturday, adding that alerts have been issued at all the country's exit points.
Two men on a motorcycle fired at least 14 shots at Batsh, an engineering lecturer, in Kuala Lumpur and killed him on the spot.

Police chief Mohamad Fuzi Bin Harun told reporters that the images of the suspects are composites based on descriptions collected by witnesses. The pictures show two light-skinned suspects who may be European or Middle Eastern. Both men are about 180 cm tall (5'9") with sturdy builds, the police chief said.
In security footage, the suspects are seen on a high-powered, dark-colored motorbike which could be a BMW or a Kawasaki. Both are carrying backpacks and have on dark jackets and helmets.
A forensic examination found that Batsh died of multiple injuries to his head and body.
"We will send some of the bullets collected to our analysis experts to determine what kind of weapon was used in this heinous killing," Fuzi said.
He said they were not sure whether the men were still in Malaysia.
"We can't close off our exits and we don't have any other information apart from the photofit," he said.
Deputy Prime Minister Ahmad Zahid Hamidi said on Saturday the suspects were believed to be Europeans with links to a foreign intelligence agency.
In Israel, Defense Minister Avigdor Lieberman dismissed Hamas allegations that Israel's spy agency the Mossad had been involved in the hit. He said that Batsh had likely been killed as part of an internal Palestinian dispute.
Batsh's family has requested for his body to be buried in Gaza.
