A massive earthquake rocked southern Turkey and northern Syria on Monday, leaving thousands dead. The disaster caused Turkish stocks to slide amid the uncertainty.

The iShares MSCI Turkey ETF, which trades on the NASDAQ, was down 2.44% at Monday's close, trading at $33.13 a share following the disaster. The exchange-traded fund holds several dozen Turkish equities. The broader Borsa Istanbul 100 Index also fell by 1.35% after Monday's earthquake, which the U.S. Geological Survey estimated could cause over $1 billion in economic losses.

Countries around the world have rallied to the aid of the disaster-struck region, with numerous countries sending search-and-rescue teams.

President Biden released a statement saying that he and first lady Jill Biden are "deeply saddened by the news of the devastating earthquakes that have thus far claimed thousands of lives in Turkiye and Syria," Turkiye is the country's preferred official name. 

Biden added that he has "directed my team to closely monitor the situation in coordination" with the Turkish government and "provide any and all needed assistance."
