Sanaa, March 30, (RHC), -- The ongoing crisis in Yemen has triggered concerns among the international community as more countries evacuated their nationals from the conflict-torn nation, Xinhua reports.

China has sent a naval fleet to help evacuate hundreds of its nationals from Yemen as the situation continues to deteriorate.

On Sunday night, a Pakistani plane moved 503 nationals out of Yemen.

Meanwhile, Indian Foreign Minister Sushma Swaraj said Sunday that evacuation would take place despite the bombing of the country's main international airport.

Saudi Arabia on Saturday evacuated 86 Arab and Western diplomats from Yemen, and the United Nations pulled its staff out of the country's capital Sanaa as well.

Yemen is currently suffering from political unrest and clashes between Houthi rebels and forces loyal to Yemeni President Abd-Rabbo Mansour Hadi, who has fled the country.

Meanwhile, a Saudi-led coalition of Arab states, which launched airstrikes on Houthi positions in Yemen as from Thursday, continued to rain bombs on key military targets on Sunday.
