DAVAO CITY—Another Chinese aircraft landed here Saturday noon to refuel, a Philippine Air Force unit said hours after the foreign plane jetted off from the lone airport in President Rodrigo Duterte's hometown.

The Chinese aircraft landed at the Francisco Bangoy International Airport at 12:18 p.m. and left at 12:59 p.m., Tactical Operations Group 11 of the Philippine Air Force told ABS-CBN News without citing the name of the particular aircraft.

The aircraft refueled at the airport before it took off for China, the unit said.

Officials did not clarify if the aircraft was the same military plane that landed here last June 9.

Last month, Presidential spokesperson Harry Roque said a Chinese aircraft bound for Australia sought permission from the Department of Foreign Affairs to make a technical stop here.

The Philippines is extended the same courtesy by other states when it needs to make technical stops, Roque said.

Minority senators have filed a resolution to probe the alleged frequent landing of Chinese military plane in the President's hometown.

"When it comes to our national interest, our national security, they should at least give it a chance to be investigated," opposition Senator Antonio Trillanes IV said in an interview on ANC's Headstart.

"The fact that it’s a cargo plane, most probably they unloaded some precious cargo. We’re trying to verify on the ground what was unloaded," he added.
