'Complete and total' ceasefire between Israel and Iran comes into effect

US President Donald Trump has announced in a social media post that a ceasefire between Israel and Iran came into effect on Tuesday morning.

Trump had earlier in the night said a ceasefire had been fully agreed and was set to begin a few hours later.

In the hours after Trump's initial announcement, Israel and Iran continued to launch airstrikes against each other, in which four people were killed in Israel and nine in Iran, according to authorities in two countries.

Iranian state media later proclaimed that a ceasefire had indeed come into effect, as did the Israeli government in a statement of its own.

Both parties reportedly paused their military operations on Tuesday morning, ending what Trump has dubbed the 12-day war.

He said the ceasefire was co-brokered with Qatar, with Emir Tamim bin Hamad al-Thani playing a crucial role in securing the truce.

The announcement came ahead of the U.S. president's departure for The Hague to attend the NATO summit.
