Former Yemeni President Ali Abdullah Saleh was admitted Sunday to a military hospital in Sanaa, the second time that he's been to a hospital this month, a government official said.

Saleh led Yemen for 30 years before stepping down, amid widespread protests as well as international pressure, last November as part of a long discussed deal brokered the six-nation Gulf Cooperation Council

He suffered extensive burns and a collapsed lung in a June 2011 strike on the mosque in Yemen's presidential compound, a U.S. government official said then. In subsequent months, he has gotten continued medical treatment in various places, including in Saudi Arabia and New York.

The Yemeni official said Sunday that Saleh was in the hospital for "a scheduled checkup, not an emergency," while acknowledging he continues to face health issues.
