SHARIFF AGUAK, Maguindanao del Sur — Authorities here are now conducting manhunt operations against two individuals — riding tandem on a motorbike — who ambushed and killed a Saudi national and injured his wife on Tuesday night.

Shariff Aguak Mayor Datu Akmad Mitra Ampatuan condemned on Wednesday the ambush and directed the police to identify, arrest and prosecute the perpetrators.

Major Haron Macabanding, town police chief, identified the slain foreigner as Saudi Solayman Jamal while his wife — identified as Bainot Jamal — suffered injuries.

Both are residents of Datu Piang in Maguindanao del Sur.

Macabanding said Jamal, who was driving his pickup truck, was killed on the spot while his wife sustained gunshot wounds in the body during the 6 p.m. attack.

The wife's unidentified brother who was seated in the back seat was unharmed and rushed his injured sister to the Maguindanao provincial hospital aboard a tricycle.

The couple had just visited a farm lot they recently purchased in neighboring Barangay Labu-Labu, Datu Hofer town, and was heading for home via this town when ambushed by the gunmen.

Initial investigation disclosed that the gunmen were seen tailing the pick-up truck and executed the ambush.

Macabanding said the motive of the attack and the identities of the perpetrators remained unknown as of posting.
