The Phnom Penh Municipal Court yesterday sentenced  six students, including two 15-year-old girls, to prison terms of one to two years    for drug-related offences. Presiding Judge Kor Vandy jailed 20-year-old So Seng Chhay and 18-year-old Thai Visal for two years for drug trafficking and drug use,  while 17-year-old Sok Phanha and 18-year-old Khun Veasna received one-year sentences for the same offences. Two girls, both 15, were sentenced to one year in jail for being accomplices.
