U.S. Treasury yields rose on Friday, erasing earlier losses, in the wake of Israeli airstrikes on Iran.

The yield on the benchmark 10-year Treasury moved 1.6 basis points higher to 4.373% at 6:22 a.m. ET. Yields on 2- and 5-year notes were around 2.1 basis points higher, while long-dated Treasurys also nudged higher.  

One basis point equals 0.01%. Bond yields and prices move in opposite directions.

The moves come after Israel launched a series of airstrikes on Iranian soil, saying sites linked to Iran's nuclear program had been targeted. The attack killed Mohammad Hossein Bagheri, head of the Iranian Armed Forces, as well as Hossein Salami, chief of Iran's Islamic Revolutionary Guard Corps, according to Iranian state media.

Two of Iran's top nuclear scientists were also reportedly killed in the airstrikes.

Ali Khamenei, Iran's supreme leader, vowed to respond to the strikes. A state of emergency was declared in Israel as the attacks began, with civilians warned that a missile and drone attack against Israel was anticipated to happen "in the immediate future."
