MANILA - At least seven people were killed overnight in separate anti-drug operations and suspected summary executions across Metro Manila.

In Quezon City, three motorcycle-riding gunmen shot dead a resident in the middle of a card game at his neighbor's wake.

Left beside victim Rowel Cruz was a piece of paper claiming that he was a drug pusher.

The gun attack also left another resident wounded.

At a nearby campsite in Barangay Payatas, another suspected victim of summary execution was found dead. Beside him was a placard stating, "Baka ikanta mo kami ang tumira."
