Asian equities were mostly lower on Thursday following a sharp selloff on Wall Street overnight and an escalation of political turmoil in Yemen.

Technology shares led the declines following a more than 2 percent slide on the Nasdaq Composite (NASDAQ: .IXIC). The biotech and semiconductor sector bore the brunt of losses overnight, with analysts citing fears of lower earnings due to the dollar’s recent strength. Meanwhile, the Dow Jones Industrial Average (Dow Jones Global Indexes: .DJI) and S&P 500 (CME:Index and Options Market: .INX) both ended over 1 percent lower on weak February durable goods orders.

Oil prices surged as much as 5 percent on Thursday after Saudi Arabia announced it began military operations in Yemen. The operation involves 10 countries, including Gulf nations, and is aimed at fighting Houthi militants who want to topple the government. Yemeni President Abed Rabbo Mansour Hadi reportedly fled Aden on Wednesday as militants moved closer to the city.
