The Indian government announced on April 30 the closure of airspace for Pakistan airlines.
The announcement was made by India a few days after Pakistan also banned Indian airlines from flying through its territory after 26 people were killed in an attack on tourists in Kashmir.
The Indian government said the ban will take effect from April 30 to May 23.
Pakistan Prime Minister Shehbaz Sharif held a phone call with US Secretary of State Marco Rubio on the evening of April 30, stressing that he was "completely opposed to India's efforts to link Pakistan to the incident," the Sharif office said in a statement.
He called for a transparent, reliable and neutral investigation and urged the US to discuss with India about the statement.
Reuters pointed out that the impact of the ban on Pakistan's aviation industry may be smaller than India's because only Pakistan International Airlines operates flights to Kuala Lumpur via India.
Pakistan Airlines also announced on April 29 that it would avoid Indian airspace after rising bilateral tensions.
Last week, Pakistan closed airspace with airlines owned or operated by India, suspended all trade, including through third countries, and stopped issuing South Asian visas, especially to Indian citizens.
On April 30, Pakistan said it had "reliable intelligence" that India intended to soon take military action amid escalating tensions between the two neighbors following the deadly attack on tourists.
India has identified three attackers, including two Pakistan citizens, as terrorists conducting a violent rebellion in Kashmir, where a majority of people are Hoiarian. Islamabad has denied any role and called for a neutral investigation.
Since the attack, the two neighbors have taken several measures, including suspending the Indus River Treaty.
