The documents span the period of time from 2009 until the breakout of the conflict in the country in March 2015.
"The documents reveal, among other things, procurement of many different weapon types: [aircraft], vessels, vehicles, proposals for [maritime] border security control and Yemeni procurement of US biometric systems," WikiLeaks said.
The US embassy in Yemen closed in February 2015 — just a month before the conflict erupted.
Yemen has been engulfed in a violent conflict between the government headed by Hadi and the Houthi movement, the country`s main opposition force backed by army units loyal to former Yemeni President Ali Abdullah Saleh.
Since March 2015, the Saudi-led coalition of mostly Persian Gulf countries has been carrying out airstrikes against the Houthis at Hadi`s request.
