MANILA - The camp of United Nationalist Alliance (UNA) standard- bearer Vice President Jejomar Binay on Friday accused presidential rival Rodrigo Duterte of hitting "below the belt" when the tough-talking mayor included Binay's family members in his attacks during one of his campaign sorties.

Binay's spokesperson Atty. Rico Quicho said Duterte should answer his own issues and controversies rather than pick on the family members of the Vice President.

"Ganyan talaga kapag hindi masagot ang mga akusasyon sa kanya, below the belt na ang mga patama," Quicho said.

Binay on Thursday expressed disppointment with Duterte for judging him and his family, despite being a lawyer.

Duterte had criticized the Binay dynasty, saying all members of the Binay family are corrupt.

Binay also warned the public about the mayor's promise to rid the country of crime in three to six months, saying Duterte would try to accomplish this with his brand of justice in Davao City -- through extrajudicial killings.

The Vice President's camp believes the presidential election is far from being a two-way race between Duterte and Senator Grace Poe.

"Dikit po ang laban. Ang aming mga core network ay unti-unti nang nagpapakita ng lakas," Quicho said.

'BERDUGO, EXECUTIONER'

Binay continued his offensive against Duterte, calling him an "executioner" who only kills poor people.

"Mister berdugo, ako ay pro-life at ang aking ginagawa ay para gumanda ang buhay ng mahihirap. Ikaw naman, pumapatay ka ng mahirap," Binay said.

"Pumapatay ka ng walang pakundangan ng mga bata at magkakapatid. Sanay kang pumatay ng mahirap dahil alam mong hindi sila makakalaban sa iyo. Kaya naman hindi ka pumapatay ng mayaman kasi alam mo lalabanan ka nila," he added.

CAN BRIAN CAMPAIGN?

Meanwhile, Quicho called the attention of the Commission on Elections (Comelec) to check the legality of Poe's son, Brian, who has been campaigning for his mother and whose video entertaining the crowd in a sortie has gone viral.

Brian Llamanzares is reported to be still an American citizen.

"Kung bawal mangampanya ang isang foreigner, dapat ay siyasatin ito ng Comelec," said Quicho. "Kung may paglabag ay dapat kuhanin ang kanilang panig."
