(Bloomberg) -- Pakistani authorities have placed former premier Imran Khan, his wife and dozens of party workers on a no-fly list, barring them from leaving the country, the latest crackdown in a stand-off with the government and the powerful military. 

The government has imposed a temporary ban that can become permanent after an investigation into the nature of cases against them, Rana Sanaullah, interior minister, told reporters on Friday in Islamabad. 

The South Asian nation has seen its political turmoil intensify as Khan’s supporters attacked army properties this month after a brief arrest of the leader. The deepening political crisis is unfolding as Pakistan grapples with its worst economic distress in decades with default risks rising amid a stalled loan program with the International Monetary Fund.

Over 10,000 supporters have been arrested across the nation, according to Khan. Pakistan is also considering to ban his political party. 

Pakistan’s military plans to try the protesters in military court with 16 individuals handed over to the army for trials on May 25. The accused can face 3-14 years in jail under the army’s law, said Sanaullah.
