Israel's national trade union is holding a nationwide strike to protest generic drugmaker Teva's decision to lay off a quarter of its workforce. Israel-based Teva announced last Thursday that it was cutting 14,000 jobs worldwide, including 1,700 jobs in Israel.

The company is considered a national treasure and is one of the largest private-sector employers. The strike, set to end at noon, halted operations at Israel's main international airport and seaports on Sunday morning.

Banks and government services were closed, and hospitals scaled back operations. In Jerusalem, dozens of protesters blocked traffic near the entrance to a Teva plant.

Some held placards saying, ""Bring the failed management of Teva to justice." Jerusalem's mayor, Nir Barkat, joined the protest, telling workers he would do everything possible to keep the plant open.
