New Delhi, July 3 -- International crude oil prices dropped Thursday morning due to weakening demand indicators from the US, reversing gains from the previous session, experts said.

Crude oil inventory in the US rose by 3.8 million barrels to 419 million barrels in the week ending 27 June, according data from the US Energy Information Administration, raising concerns of a weakening demand in the world's largest economy and the largest consumer of oil.

Also, gasoline demand during the week under review fell to 8.6 million barrels per day from 9.7 million barrels a week ago raising demand fears amid the ongoing summer driving season in the US.
