The scope of the ongoing crisis in Syria is made clear yet again by two new reports from the United Nations:

-- An estimated 1.5 million Syrians have been "internally displaced" because of the fighting between forces loyal to President Bashar Assad and those who oppose him, according to Chaloka Beyani. He is the U.N.'s special rapporteur on the human rights of internally displaced persons.

The figure refers to "persons or groups of persons who have been forced or obliged to flee or to leave their homes or places of habitual residence, in particular as a result of or in order to avoid the effects of armed conflict, situations of generalised violence, violations of human rights or natural or human-made disasters, and who have not crossed an internationally recognised state border," according to the Internal Displacement Monitoring Center.

According to the CIA's World Factbook, there are about 22.5 million people in Syria. So, about 6.7 percent of the population has been uprooted.

-- As of Thursday, 146,667 Syrians had sought help at refugee camps in Lebanon, Turkey, Jordan and Iraq. The largest number — more than 50,000 — are in Turkey.
