A fresh gunbattle erupted Sunday at the Indian Air Force base in Pathankot, where 11 people died in an attack by suspected Islamic militants, police said.
Officers said they believe up to two gunmen were hiding inside the air base in the northern state of Punjab near the border with Pakistan, which came under attack on Saturday.
"We suspect one or two terrorists are hiding inside. They are firing intermittently," Pathankot police chief Kunwar Vijay Partap Singh told AFP.
