The new government then pursued a policy of "war for peace". Determined to retake the key rebel stronghold of Jaffna, which was occupied by 2,000 rebels, it poured troops into the peninsula in the successful Operation Riviresa. In one particular incident in August 1995, Air Force jets bombed St. Peter's church at Navali (Naavaella), killing at least 65 refugees and wounding 150 others. In another instance in the same year, over 40 people were massacred in Nagerkovil and more civilian massacres followed in subsequent years, such as the Kumarapuram massacre, Tampalakamam massacre, Puthukkudiyiruppu massacre, etc., all of them carried out by government forces. Government troops initially cut off the peninsula from the rest of the island, and then, after seven weeks of heavy fighting, succeeded in bringing Jaffna under government control for the first time in nearly a decade. In a high-profile ceremony, Sri Lankan Defense Minister Col. Anuruddha Ratwatte raised the national flag inside the Jaffna Fort on 5 December 1995. The government estimated that approximately 2500 soldiers and rebels were killed in the offensive, and an estimated 7,000 wounded. Many civilians were killed in this conflict, such as the Navaly church bombing in which over 125 civilians died. The LTTE and more than 350,000 civilians, compelled by LTTE pressure to leave Jaffna, fled to the Vanni region in the interior. Most of the refugees returned later the next year.
