Here we go again. Francis X. Taylor, under-secretary for intelligence and analysis at the Department of Homeland Security, testified before the Senate Committee on Homeland Security on Sept. 10 that operatives of the extremist jihadi movement variously known as ISIS, ISIL or the Islamic State have discussed infiltrating the United States through the Mexican border. "There have been Twitter and social-media exchanges among ISIL adherents across the globe speaking about that as a possibility," Taylor said in response to a question from Sen. John McCain, who wanted to know if any ISIS chatter had been intercepted that "would urge infiltration into the United States across our Southwestern border." But Taylor said he was "satisfied that we have the intelligence and the capability at our border that would prevent that activity." And when pressed further, he admitted: "At present, DHS is unaware of any specific, credible threat to the US homeland from ISIL."

Guerillas affiliated with the Democratic Party of Iranian Kurdistan (PDKI) have for the past days been clashing with Iranian military forces in the area of Shino (Oshnavieh, West Azerbaijan province), leaving a senior army commander dead.  Iran's official media on Sept. 26 confirmed the killing of the commander, named as Sajad Takhti, by the guerilla force known as the Peshmerga of Iranian Kurdistan. The PDKI also confirmed that one of their fighters has been killed  in the area. Fighting is also reported in the Kurdish city of Mariwan (Kordistan province) on the border of Iran and Iraq's Kurdistan Region. (BasNews, Sept. 27)

The US-led coalition launched its first air-strikes targeting ISIS positions on the outskirts of the besieged Kurdish town of Kobani on Sept. 27, according to local officials. The strike follows a week-long ISIS offensive that has driven over 140,000 Syrian Kurds across the Turkish border. Ahmed Sulaiman, an official of the Democratic Union Party (PYD), told Kurdish news agency Rudaw that the mission targeted ISIS forces based at several villages east of Kobani, including Jim-Hiran, Ali-Shar, Mirde Smill and Sheran. The PKK-aligned People's Protection Units (YPG) are defending the town, and have issued a statement vowing to "make Kobani the graveyard of ISIS fighters." (Rudaw, Sept. 27)

The Sept. 23 US air-strikes on the so-called "Khorasan Group" near Aleppo on Sept. 23 killed 50 al-Qaeda militants and eight civilians—including three children and a woman—according to the Syrian Observatory for Human Rights. The Pentagon said the strikes on the Khorasan Group "were undertaken only by US assets," while strikes against ISIS elsewhere in Syria included warplanes from Arab coalition members. (Daily Star, Sept. 23) The Syrian Observatory for Human Rights also reports that ISIS has recruited more than 6,000 new fighters since the US air-strikes began. One of Washington's favored rebel factions, Harakat Hazm, part of the Free Syrian Army alliance and a recipient of US missiles, issued a statement on Twitter denouncing the "external intervention"—meaning the US-led bombing campaign—as "an attack on the revolution." The group is demanding "unconditional arming" of the Free Syrian Army as an alternative to the air raids.

The US-led coalition carried out air-strikes against both ISIS and Nusra Front positions in Syria on Sept. 23. At the same time, US planes took unilateral action against the so-called "Khorasan Group" of ex-Qaeda members "to disrupt the imminent attack plotting against the United States and Western interests," as a Central Command statement put it. The statement provided no details on the plotting. The Khorasan Group targets were said to be near Aleppo. Reports indicate the group is led by Muhsin al-Fadhli, a Qaeda operative who was supposedly privy to Osama bin Laden's 9-11 plans prior to the attack. The US State Department calls al-Fadhli a "senior facilitator and financier" for al-Qaeda. (Times of Israel, MJ) Meanwhile, the Israeli military shot down a Syrian MiG-21 fighter jet that it said had infiltrated it airspace over the Golan Heights. The wreckage fell on the Syrian-controlled side of the plateau.

The US carried out its first air-strikes against ISIS targets in Syria on Sept. 22. In a statement, Pentagon press secretary Rear Adm. John Kirby said the US used "a mix of fighter, bomber and Tomahawk Land Attack Missiles" launched from the USS George HW Bush in the Persian Gulf. Kirby said that because these strikes are ongoing, he could not give details about where they took place. But an unnamed Pentagon official told NPR the strikes targeted positions near Raqqa, the ISIS de facto capital. Planes from five Arab countries participated in the strikes—also not named by Kirby, although FoxNews identified them as Saudi Arabia, the United Arab Emirates, Jordan, Bahrain and Qatar. There was no indication that the Syrian government had been consulted on the strikes, as Damascus had demanded.

News agencies in the Middle East report that ISIS militants have destroyed the Armenian Genocide Memorial Church in Der Zor, the Syrian site where Turkish forces established concentration camps for deported Armenians during World War I—known as the "Auschwitz of the Armenian Genocide." The reports surfaced as Armenia was celebrating the 23rd anniversary of its independence Sept. 21. Armenia's Foreign Minister Edward Nalbandian issued a statement calling the destruction of the church a "horrible barbarity." The church was built in 1990, and consecrated a year later. A memorial and  museum housing remains of the genocide victims was also built in the church compound. Thousands of Armenians from Syria and neighboring countries gathered at the memorial every year on April 24 to commemorate the genocide. Hundreds of thousands of Armenians perished in Der Zor and the surrounding desert during the genocide. (Armenian Weekly, Sept. 21)

The UN refugee agency reports that up to 70,000 Syrian Kurds have crossed into Turkey over the past 24 hours to escape the ISIS advance on the town of Kobani (Ayn al-Arab). A Kurdish commander on the ground said ISIS forces had advanced to within 15 kilometers of the town. Most of the refugees are women, children and the elderly. Turkey opened a stretch of the border to allow the refugees to cross over. But Turkish security forces later fired water cannon and tear-gas at crowds that gathered in support of the refugees on the border. Authorities said they wanted to stop Kurdish PKK fighters entering Syria, while local TV said Kurds had been trying to deliver aid. (AP, Reuters, Al Jazeera, BBC News)
