During his vacation on Martha's Vineyard, Obama said he and Vice President Biden had called and congratulated Abadi earlier in the day.
"The only lasting solution is for Iraqis to come together and form an inclusive government," the president said.
Obama also noted that the U.S. is ready to work with other countries in the region to help address the humanitarian issues in Iraq.
On the humanitarian missions in northern Iraq, where militants have forced people up into the mountains without food and water, we've already posted some videos that are worth watching. And in case you missed it, we also have background on an earlier U.S. humanitarian aid mission in the region and what lesson could be learned from that response.
