The U.S. Department of Justice said Friday six people had been charged over an alleged attempt to send money and military supplies to militant groups in Iraq and Syria, including to IS jihadists.

According to the indictment, which was made public on Friday, five of the defendants are in the United States and have been arrested, while a sixth is overseas. They are charged with conspiracy to provide support to terrorist organizations.

More than 30 jihadists in the Islamic State group were killed Friday in air strikes on Syria by warplanes of the U.S.-led coalition, the Syrian Observatory for Human Rights said.

"At least 30 jihadists, and certainly more, were killed in coalition raids on Friday against positions and depots sheltering military vehicles and tanks, east and west of the city of Raqa," the self-proclaimed IS capital, the Britain-based monitor said.

Saudi Arabia on Friday postponed for a fourth straight week the flogging of blogger Raef Badawi who was sentenced to 1,000 lashes for insulting Islam, his wife said.

Ensaf Haidar told AFP that he was not flogged, but she did "not know the reasons".

The Islamic State group said a coalition air strike Friday killed an American woman it was holding hostage in Syria, in a claim that could not be immediately verified.

In Jordan, meanwhile, thousands of people marched to demand retribution against IS for murdering a captive pilot.

Palestinian resistance veteran and two-time plane hijacker Leila Khaled condemned Friday the burning to death of a Jordanian pilot by the Islamic State group, calling the act "terrorism".

"We denounce this in all languages," said Khaled during a visit to South Africa. 

The horrifying images of a Jordanian pilot burned alive by the Islamic State group this week has put added pressure on the US to ensure rapid rescue operations for its partners.

U.S. officials confirmed last month that the United Arab Emirates -- nicknamed "Little Sparta" for its initial eagerness to enter the fray against Islamic State -- had pulled out of the U.S.-led air campaign over concerns about rescue operations. 

Huthis who have seized Yemen's capital announced Friday they had dissolved parliament and installed a "presidential council" to run the country in the face of a power vacuum.

The Huthi militia said it would set up a national council of 551 members to replace the legislature in the violence-wracked country, a key US ally in the fight against al-Qaida.

King Abdullah II of Jordan, a member of the U.S.-led coalition battling the Islamic State group, faces the toughest challenge of his 16-year reign after IS murdered a downed pilot.

One of Washington's closest allies in the region, Abdullah was catapulted into the forefront of the conflict with the jihadists after IS burned the captured Jordanian airman alive.

Syrian Kurdish fighters have seized dozens of villages from Islamic State group jihadists around the town of Kobane on the Turkish border, expanding their control in the area, a monitor said Friday.

The Kurdish People's Protection Units (YPG) had captured 101 villages around Kobane since seizing it from IS on January 26 after four months of fighting, the Syrian Observatory for Human Rights said.

A secular-led coalition government that includes Islamists took office in Tunisia Friday, three months after the North African state's first free parliamentary elections.
