Israeli planes struck a Syrian military base housing missiles, a White House official tells CNN; Israel was reportedly concerned the missiles—which the AP says were of Russian origin—could be passed to Hezbollah. Israel's government hasn't confirmed the attack, though regional reports pointed to a blast at the site near Latakia, a port city. It's unclear whether the attack occurred last night or tonight. Israel has reportedly hit Syrian missiles at least twice already this year, the AP notes, though Israel hasn't confirmed it. The latest reports follow news that Syria reportedly met a major deadline for destroying chemical weapons.
