Trump says he will make a decision on whether to attack Iran within two weeks

US President Donald Trump on Thursday said he will decide whether to attack Iran within a fortnight, as Israel and Iran continued to trade fire for a seventh day after Israel launched unprovoked attacks on Iran beginning on 13 June.

"Based on the fact that there's a substantial chance of negotiations that may or may not take place with Iran in the near future, I will make my decision whether or not to go within the next two weeks," Trump said in a statement read out by his press secretary, Karoline Leavitt.

Trump has kept the world guessing with cryptic social media posts over whether the US would directly intervene. The US is currently involved in a defensive capacity, with its air defence systems intercepting Iranian missiles targeting Israel.
