A third crude tank caught fire and collapsed at Cuba's main oil terminal Matanzas, as an oil spill spread flames from a second tank that caught fire two days earlier, Reuters reported citing a local governor.

Mario Sabines, governor of the Matanzas province, said that with the help from Mexico and Venezuela, Cuba had made progress in fighting off the raging flames over the weekend, although the fire began spreading from the second tank late on Sunday.

According to the Reuters report, Sabines compared the situation to an "Olympic torch" going from one tank to the next, turning each into a "caldron" and now encompassing the area covering three tanks and with flames and billowing black smoke making tackling the situation "complicated".

Residents also expressed fear that the crisis will worsen as the hottest months of the year approach.
