DJIBOUTI, March 30 -- The first group of 122 Chinese evacuees from conflict-ridden Yemen on Sunday night arrived at the Djibouti port as the situation continues to deteriorate in Yemen.

A People's Liberation Army Navy fleet, which had been carrying out escort missions in the Gulf of Aden and Somali waters, was dispatched for the evacuation on Sunday, according to China's Ministry of National Defense.

The remaining more than 400 Chinese nationals on Monday left the Yemeni coastal city of Al-Hodayda aboard a Chinese navy frigate and are expected to arrive in Djibouti on Monday night.

Security sharply deteriorated in Yemen since early March when conflicts erupted in several provinces in the country's southern regions.

The Shiite Houthi group launched attacks on Aden city, which President Abd-Rabbu Mansour Hadi declared as temporary capital after he fled weeks of house arrest by the Houthis in Sanaa.

Last Thursday, a Saudi-led coalition started airstrikes on Houthi targets in Sanaa and other cities, saying the multinational action was to protect Hadi's legitimacy and force the Houthis to retreat from cities it seized since September 2014.
