MANILA, Rabi'I 28, 1438, December 27, 2016, SPA -- Philippine authorities have seized about 6 billion pesos ($120 million) worth of methamphetamines in a series of anti-narcotics operations this month that have yielded the biggest haul in the country's history, the justice minister said on Tuesday, according to Reuters. The National Bureau of Investigation (NBI) conducted the operations, including one on Monday in San Juan City in the capital Manila where drums of chemicals used to produce methamphetamines, or "shabu" as it is known, were seized. That followed a raid on Friday in a quiet neighbourhood in the same city, when six people were arrested and 560 kg (1,200 lb) of suspected methamphetamines was found, worth an estimated $67 million. "It is not only the biggest haul this year, but the biggest so far in history," Justice Secretary Vitaliano Aguirre said in a news conference. --SPA 15:36 LOCAL TIME 12:36 GMT www.spa.gov.sa/w299427
