**Obama Sending 275 US Military Personnel to Iraq**
President Barack Obama has ordered 275 U.S. military personnel to Iraq to help provide security to the embassy in Baghdad and U.S. personnel there.
Mr. Obama's notification to Congress Monday says the move has the consent of the Iraqi government.
While the president has ruled out sending ground forces back into Iraq, he met with his national security team Monday to consider other options.
They include possible air strikes against the Sunni militants who already control large parts of northern Iraq and have vowed to seize Baghdad from the Shiite-led government.
The U.S. also is considering working with Iran. But the Pentagon says it has no plans to enter into military cooperation with the Iranians in any action in Iraq.
A top State Department official says U.S. and Iranian diplomats met briefly Monday on the sidelines of nuclear talks in Vienna. The official says talks with the Iranians will not include any discussion of military coordination.
**Ukraine President Promises to Regain Control of Frontier**
Ukraine's President Petro Poroshenko says he has ordered the army to take "decisive actions" this week to regain control of the Ukrainian-Russian frontier.
In an address Monday to top security officials, Mr. Poroshenko said he expects the military push to last no more than a week, and he said it will pave the way for a truce and peace talks with pro-Russian separatists.
He also said Ukrainian troops have regained control of a little more than 10 percent of the border, and that checkpoints are in place aimed at stopping the flow of Russian military hardware into his country.
The Poroshenko address came hours after Russian energy giant Gazprom cut natural gas shipments to its energy dependent neighbor, after Kyiv missed a deadline to paydown a nearly $2 billion energy debt.
Ukraine, which showed no public signs Monday of softening its demands, says it has almost 14 billion cubic meters of gas in underground storage -- enough to meet its needs until December.
