Lebanon, DRC-Rwanda, Iraq.

Today's three stories you should know.

Lebanon

Two years ago today, a huge explosion tore through the port in Lebanon’s capital Beirut, destroying large parts of the city and leaving more than 200 people dead. But all this time later, the families of those who were killed are still fighting for justice. An official investigation has been stalled time and time again, often by politicians accused of failing to prevent the disaster from happening. Today, the families marched through Beirut again calling for those responsible to be held to account. “We know that this state is corrupted and this state did this crime: they killed our parents, they broke our homes, they are the ones that are guilty,” one marcher told Al Jazeera.

DRC-Rwanda

Rwandan troops have been operating alongside a rebel group in the eastern Democratic Republic of the Congo (DRC), according to UN experts. As mentioned in several recent newsletters, a group known as the M23 has stepped up an armed campaign against DRC’s government in recent months, killing many people and sending thousands fleeing. Congo has repeatedly accused Rwanda of involvement and Rwanda has repeatedly denied the claims. But a new report to the UN Security Council, seen by the Associated Press, accuses Kigali of “direct intervention” in the affairs of its neighbor. Relations between the two nations have been dire for decades.

Iraq

Thousands of public sector workers in Iraq were given the day off today after temperatures breached 50C (122F) in several parts of the country. Work was called off in at least 10 provinces and in the southern port of Basra, where temperatures were especially high, a four-day holiday was declared. Extreme heat is not unusual in Iraq but locals say it is getting hotter. Dust storms have also plagued the country this year.
