Washington, Apr 21: Known for his gaffes, US President Donald Trump yet again committed a faux pas on Sunday as he erroneously wrote that "138 million people" were killed in a string of blasts in Sri Lanka.The near-simultaneous attacks on Easter Sunday at three churches and as many luxury hotels frequented by foreigners killed more than 160 people and injured over 450 others, shattering a decade of peace in the country after the end of the brutal civil war with the LTTE.President Trump offered "heartfelt condolences" to the people of Sri Lanka and said the US stood ready to help.The US leader, however, erroneously wrote that "138 million people" were killed in the attacks instead of just 138."Heartfelt condolences from the people of the United States to the people of Sri Lanka on the horrible terrorist attacks on churches and hotels that have killed at least 138 million people and badly injured 600 more.

We are now an empty Country as per Donald!!" tweeted another follower.Sri Lanka has a total population of around 21.7 million.Trump is known for his wrong tweets and for using embarrassing nicknames as well as 'mispronouncing names' of people such as "Jeff Bozo" in reference to Jeff Bezos of Amazon.In March, he mistakenly referred to Apple CEO Tim Cook as "Tim Apple", a verbal slip which netizens poked fun at by sharing rib-tickling memes on social media.Last year, he had called Lockheed Martin CEO Marillyn Hewson "Marillyn Lockheed.
