JERUSALEM –  Israel's Defense Ministry says it has launched a new observation satellite into orbit.

Israel announced the launch of the "Ofek 10" late Wednesday. The launch was carried out with state-owned Israel Aircraft Industries.

The Ofek 10 is the latest in a line of spy satellites built by Israel Aircraft Industries for the government. Israel is expected to use the satellite to keep tabs on Iran and hostile militant groups in the region.

Israel believes Iran is trying to develop a nuclear weapon — a charge Iran denies — and accuses it of arming militants across the region.
