This phase of the war soon acquired the name "Eelam War II", and featured unprecedented brutality. On 11 June 1990 the LTTE massacred 600 policemen in the Eastern Province after they had surrendered on promises of safe-conduct. The government placed an embargo on food and medicine entering the Jaffna peninsula and the air force relentlessly bombed LTTE targets in the area. The LTTE responded by attacking Sinhalese and Muslim villages and massacring civilians. One of the largest civilian massacres of the war occurred when the LTTE massacred 166 Muslim civilians at Palliyagodella. The government trained and armed Home Guard Muslim units.
