Speaking to reporters, Union Civil Aviation Minister Praful Patel said security was being tightened across all the airports in order to avoid any terror activities.
Patel further said that the government has taken the Kingfisher bomb case seriously and are probing into the same.
"Airports are usually and always in a state of high alert. But in view of the recent incident, the Bureau of Civil Aviation has further heightened security across all the airports in the country. Security will not be compromised at all," he said.
An early morning Kingfisher flight from Bangalore to Thiruvananthapuram carried the crude explosive undetected. The cricket ball-type device was detected only at Thiruvananthapuram.
"Investigations have been ordered and we consider it as a major breach of security, therefore every possible action to unearth the cause will be undertaken," Patel added.
